Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16684, here are decompositions:
- 11 + 16673 = 16684
- 23 + 16661 = 16684
- 53 + 16631 = 16684
- 131 + 16553 = 16684
- 137 + 16547 = 16684
- 191 + 16493 = 16684
- 197 + 16487 = 16684
- 233 + 16451 = 16684
Showing the first eight; more decompositions exist.

The digit sequence 16684 first appears in π at position 167,412 of the decimal expansion (the 167,412ordinal-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.
