Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2064, here are decompositions:
- 11 + 2053 = 2064
- 37 + 2027 = 2064
- 47 + 2017 = 2064
- 53 + 2011 = 2064
- 61 + 2003 = 2064
- 67 + 1997 = 2064
- 71 + 1993 = 2064
- 113 + 1951 = 2064
Showing the first eight; more decompositions exist.

The digit sequence 2064 first appears in π at position 41,764 of the decimal expansion (the 41,764ordinal-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.
