Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564562, here are decompositions:
- 31 + 31564531 = 31564562
- 61 + 31564501 = 31564562
- 103 + 31564459 = 31564562
- 229 + 31564333 = 31564562
- 241 + 31564321 = 31564562
- 313 + 31564249 = 31564562
- 433 + 31564129 = 31564562
- 613 + 31563949 = 31564562
Showing the first eight; more decompositions exist.
