Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27770, here are decompositions:
- 3 + 27767 = 27770
- 7 + 27763 = 27770
- 19 + 27751 = 27770
- 31 + 27739 = 27770
- 37 + 27733 = 27770
- 73 + 27697 = 27770
- 79 + 27691 = 27770
- 97 + 27673 = 27770
Showing the first eight; more decompositions exist.
