Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931770, here are decompositions:
- 13 + 931757 = 931770
- 19 + 931751 = 931770
- 23 + 931747 = 931770
- 31 + 931739 = 931770
- 41 + 931729 = 931770
- 43 + 931727 = 931770
- 61 + 931709 = 931770
- 79 + 931691 = 931770
Showing the first eight; more decompositions exist.
