Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145746, here are decompositions:
- 23 + 145723 = 145746
- 37 + 145709 = 145746
- 43 + 145703 = 145746
- 59 + 145687 = 145746
- 67 + 145679 = 145746
- 103 + 145643 = 145746
- 109 + 145637 = 145746
- 113 + 145633 = 145746
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 145,746 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 145746 first appears in π at position 344,628 of the decimal expansion (the 344,628ordinal-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.
