Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562496, here are decompositions:
- 13 + 31562483 = 31562496
- 29 + 31562467 = 31562496
- 47 + 31562449 = 31562496
- 67 + 31562429 = 31562496
- 73 + 31562423 = 31562496
- 107 + 31562389 = 31562496
- 139 + 31562357 = 31562496
- 149 + 31562347 = 31562496
Showing the first eight; more decompositions exist.
