Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387708, here are decompositions:
- 31 + 2147387677 = 2147387708
- 61 + 2147387647 = 2147387708
- 79 + 2147387629 = 2147387708
- 409 + 2147387299 = 2147387708
- 577 + 2147387131 = 2147387708
- 691 + 2147387017 = 2147387708
- 787 + 2147386921 = 2147387708
- 997 + 2147386711 = 2147387708
Showing the first eight; more decompositions exist.
