Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145604, here are decompositions:
- 3 + 145601 = 145604
- 61 + 145543 = 145604
- 73 + 145531 = 145604
- 103 + 145501 = 145604
- 127 + 145477 = 145604
- 163 + 145441 = 145604
- 181 + 145423 = 145604
- 223 + 145381 = 145604
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 145,604 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 145604 first appears in π at position 694,590 of the decimal expansion (the 694,590ordinal-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.
