Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3864, here are decompositions:
- 11 + 3853 = 3864
- 13 + 3851 = 3864
- 17 + 3847 = 3864
- 31 + 3833 = 3864
- 41 + 3823 = 3864
- 43 + 3821 = 3864
- 61 + 3803 = 3864
- 67 + 3797 = 3864
Showing the first eight; more decompositions exist.

The digit sequence 3864 first appears in π at position 8,144 of the decimal expansion (the 8,144ordinal-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.
