Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572416, here are decompositions:
- 3 + 31572413 = 31572416
- 13 + 31572403 = 31572416
- 163 + 31572253 = 31572416
- 193 + 31572223 = 31572416
- 283 + 31572133 = 31572416
- 367 + 31572049 = 31572416
- 409 + 31572007 = 31572416
- 433 + 31571983 = 31572416
Showing the first eight; more decompositions exist.
