Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143736, here are decompositions:
- 7 + 143729 = 143736
- 17 + 143719 = 143736
- 37 + 143699 = 143736
- 59 + 143677 = 143736
- 67 + 143669 = 143736
- 83 + 143653 = 143736
- 107 + 143629 = 143736
- 127 + 143609 = 143736
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 143,736 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 143736 first appears in π at position 26,187 of the decimal expansion (the 26,187ordinal-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.
