Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515504, here are decompositions:
- 103 + 515401 = 515504
- 127 + 515377 = 515504
- 181 + 515323 = 515504
- 193 + 515311 = 515504
- 211 + 515293 = 515504
- 271 + 515233 = 515504
- 277 + 515227 = 515504
- 313 + 515191 = 515504
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 515,504 and was likely granted around 1894.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 515504 first appears in π at position 383,346 of the decimal expansion (the 383,346ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
