Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986790, here are decompositions:
- 11 + 986779 = 986790
- 23 + 986767 = 986790
- 31 + 986759 = 986790
- 41 + 986749 = 986790
- 53 + 986737 = 986790
- 61 + 986729 = 986790
- 71 + 986719 = 986790
- 73 + 986717 = 986790
Showing the first eight; more decompositions exist.
