Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6900, here are decompositions:
- 17 + 6883 = 6900
- 29 + 6871 = 6900
- 31 + 6869 = 6900
- 37 + 6863 = 6900
- 43 + 6857 = 6900
- 59 + 6841 = 6900
- 67 + 6833 = 6900
- 71 + 6829 = 6900
Showing the first eight; more decompositions exist.

The digit sequence 6900 first appears in π at position 12,172 of the decimal expansion (the 12,172ordinal-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.
