Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517182, here are decompositions:
- 293 + 31516889 = 31517182
- 401 + 31516781 = 31517182
- 479 + 31516703 = 31517182
- 563 + 31516619 = 31517182
- 569 + 31516613 = 31517182
- 659 + 31516523 = 31517182
- 821 + 31516361 = 31517182
- 863 + 31516319 = 31517182
Showing the first eight; more decompositions exist.
