Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592064, here are decompositions:
- 11 + 31592053 = 31592064
- 13 + 31592051 = 31592064
- 17 + 31592047 = 31592064
- 67 + 31591997 = 31592064
- 71 + 31591993 = 31592064
- 107 + 31591957 = 31592064
- 151 + 31591913 = 31592064
- 191 + 31591873 = 31592064
Showing the first eight; more decompositions exist.
