Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26638, here are decompositions:
- 5 + 26633 = 26638
- 11 + 26627 = 26638
- 41 + 26597 = 26638
- 47 + 26591 = 26638
- 137 + 26501 = 26638
- 149 + 26489 = 26638
- 179 + 26459 = 26638
- 239 + 26399 = 26638
Showing the first eight; more decompositions exist.

The digit sequence 26638 first appears in π at position 118,142 of the decimal expansion (the 118,142ordinal-suffix:nd 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.
