Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446, here are decompositions:
- 53 + 31393 = 31446
- 59 + 31387 = 31446
- 67 + 31379 = 31446
- 89 + 31357 = 31446
- 109 + 31337 = 31446
- 113 + 31333 = 31446
- 127 + 31319 = 31446
- 139 + 31307 = 31446
Showing the first eight; more decompositions exist.
