Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517242, here are decompositions:
- 11 + 31517231 = 31517242
- 179 + 31517063 = 31517242
- 269 + 31516973 = 31517242
- 353 + 31516889 = 31517242
- 401 + 31516841 = 31517242
- 431 + 31516811 = 31517242
- 461 + 31516781 = 31517242
- 683 + 31516559 = 31517242
Showing the first eight; more decompositions exist.
