Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143722, here are decompositions:
- 3 + 143719 = 143722
- 11 + 143711 = 143722
- 23 + 143699 = 143722
- 53 + 143669 = 143722
- 71 + 143651 = 143722
- 113 + 143609 = 143722
- 149 + 143573 = 143722
- 233 + 143489 = 143722
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 143,722 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 143722 first appears in π at position 688,344 of the decimal expansion (the 688,344ordinal-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.
