Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564292, here are decompositions:
- 31 + 31564261 = 31564292
- 43 + 31564249 = 31564292
- 163 + 31564129 = 31564292
- 241 + 31564051 = 31564292
- 283 + 31564009 = 31564292
- 313 + 31563979 = 31564292
- 349 + 31563943 = 31564292
- 421 + 31563871 = 31564292
Showing the first eight; more decompositions exist.
