Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711250, here are decompositions:
- 13 + 8711237 = 8711250
- 61 + 8711189 = 8711250
- 71 + 8711179 = 8711250
- 89 + 8711161 = 8711250
- 109 + 8711141 = 8711250
- 113 + 8711137 = 8711250
- 167 + 8711083 = 8711250
- 179 + 8711071 = 8711250
Showing the first eight; more decompositions exist.
