Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145624, here are decompositions:
- 23 + 145601 = 145624
- 47 + 145577 = 145624
- 107 + 145517 = 145624
- 113 + 145511 = 145624
- 137 + 145487 = 145624
- 173 + 145451 = 145624
- 191 + 145433 = 145624
- 233 + 145391 = 145624
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 145,624 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 145624 first appears in π at position 628,122 of the decimal expansion (the 628,122ordinal-suffix:nd 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.
