Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145704, here are decompositions:
- 17 + 145687 = 145704
- 23 + 145681 = 145704
- 43 + 145661 = 145704
- 61 + 145643 = 145704
- 67 + 145637 = 145704
- 71 + 145633 = 145704
- 101 + 145603 = 145704
- 103 + 145601 = 145704
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 145,704 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 145704 first appears in π at position 747,900 of the decimal expansion (the 747,900ordinal-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.
