Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31770, here are decompositions:
- 19 + 31751 = 31770
- 29 + 31741 = 31770
- 41 + 31729 = 31770
- 43 + 31727 = 31770
- 47 + 31723 = 31770
- 71 + 31699 = 31770
- 83 + 31687 = 31770
- 103 + 31667 = 31770
Showing the first eight; more decompositions exist.
