Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145504, here are decompositions:
- 3 + 145501 = 145504
- 17 + 145487 = 145504
- 41 + 145463 = 145504
- 53 + 145451 = 145504
- 71 + 145433 = 145504
- 113 + 145391 = 145504
- 197 + 145307 = 145504
- 251 + 145253 = 145504
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 145,504 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 145504 first appears in π at position 579,066 of the decimal expansion (the 579,066ordinal-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.
