Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87946, here are decompositions:
- 3 + 87943 = 87946
- 29 + 87917 = 87946
- 59 + 87887 = 87946
- 113 + 87833 = 87946
- 149 + 87797 = 87946
- 179 + 87767 = 87946
- 227 + 87719 = 87946
- 263 + 87683 = 87946
Showing the first eight; more decompositions exist.
