Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711388, here are decompositions:
- 5 + 8711383 = 8711388
- 11 + 8711377 = 8711388
- 29 + 8711359 = 8711388
- 31 + 8711357 = 8711388
- 41 + 8711347 = 8711388
- 151 + 8711237 = 8711388
- 199 + 8711189 = 8711388
- 227 + 8711161 = 8711388
Showing the first eight; more decompositions exist.
