Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618264, here are decompositions:
- 53 + 31618211 = 31618264
- 71 + 31618193 = 31618264
- 101 + 31618163 = 31618264
- 131 + 31618133 = 31618264
- 137 + 31618127 = 31618264
- 263 + 31618001 = 31618264
- 311 + 31617953 = 31618264
- 401 + 31617863 = 31618264
Showing the first eight; more decompositions exist.
