Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387882, here are decompositions:
- 43 + 2147387839 = 2147387882
- 61 + 2147387821 = 2147387882
- 139 + 2147387743 = 2147387882
- 163 + 2147387719 = 2147387882
- 379 + 2147387503 = 2147387882
- 499 + 2147387383 = 2147387882
- 751 + 2147387131 = 2147387882
- 823 + 2147387059 = 2147387882
Showing the first eight; more decompositions exist.
