Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6138, here are decompositions:
- 5 + 6133 = 6138
- 7 + 6131 = 6138
- 17 + 6121 = 6138
- 37 + 6101 = 6138
- 47 + 6091 = 6138
- 59 + 6079 = 6138
- 71 + 6067 = 6138
- 101 + 6037 = 6138
Showing the first eight; more decompositions exist.

The digit sequence 6138 first appears in π at position 24,497 of the decimal expansion (the 24,497ordinal-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.
