Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143622, here are decompositions:
- 5 + 143617 = 143622
- 13 + 143609 = 143622
- 29 + 143593 = 143622
- 53 + 143569 = 143622
- 71 + 143551 = 143622
- 103 + 143519 = 143622
- 109 + 143513 = 143622
- 113 + 143509 = 143622
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 143,622 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 143622 first appears in π at position 402,741 of the decimal expansion (the 402,741ordinal-suffix:st 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.
