Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507520, here are decompositions:
- 17 + 507503 = 507520
- 23 + 507497 = 507520
- 29 + 507491 = 507520
- 59 + 507461 = 507520
- 89 + 507431 = 507520
- 137 + 507383 = 507520
- 149 + 507371 = 507520
- 173 + 507347 = 507520
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 507,520 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 507520 first appears in π at position 325,512 of the decimal expansion (the 325,512ordinal-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.
