Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609910, here are decompositions:
- 61 + 31609849 = 31609910
- 97 + 31609813 = 31609910
- 151 + 31609759 = 31609910
- 349 + 31609561 = 31609910
- 379 + 31609531 = 31609910
- 457 + 31609453 = 31609910
- 571 + 31609339 = 31609910
- 643 + 31609267 = 31609910
Showing the first eight; more decompositions exist.
