Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101638, here are decompositions:
- 11 + 101627 = 101638
- 101 + 101537 = 101638
- 107 + 101531 = 101638
- 137 + 101501 = 101638
- 149 + 101489 = 101638
- 227 + 101411 = 101638
- 239 + 101399 = 101638
- 359 + 101279 = 101638
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 101,638 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 101638 first appears in π at position 444,624 of the decimal expansion (the 444,624ordinal-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.
