Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486770, here are decompositions:
- 19 + 31486751 = 31486770
- 31 + 31486739 = 31486770
- 37 + 31486733 = 31486770
- 43 + 31486727 = 31486770
- 47 + 31486723 = 31486770
- 59 + 31486711 = 31486770
- 61 + 31486709 = 31486770
- 109 + 31486661 = 31486770
Showing the first eight; more decompositions exist.
