Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624490, here are decompositions:
- 13 + 31624477 = 31624490
- 61 + 31624429 = 31624490
- 67 + 31624423 = 31624490
- 103 + 31624387 = 31624490
- 127 + 31624363 = 31624490
- 151 + 31624339 = 31624490
- 349 + 31624141 = 31624490
- 421 + 31624069 = 31624490
Showing the first eight; more decompositions exist.
