Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506446, here are decompositions:
- 3 + 31506443 = 31506446
- 73 + 31506373 = 31506446
- 79 + 31506367 = 31506446
- 163 + 31506283 = 31506446
- 199 + 31506247 = 31506446
- 457 + 31505989 = 31506446
- 463 + 31505983 = 31506446
- 487 + 31505959 = 31506446
Showing the first eight; more decompositions exist.
