Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387216, here are decompositions:
- 3 + 2147387213 = 2147387216
- 157 + 2147387059 = 2147387216
- 199 + 2147387017 = 2147387216
- 229 + 2147386987 = 2147387216
- 463 + 2147386753 = 2147387216
- 487 + 2147386729 = 2147387216
- 577 + 2147386639 = 2147387216
- 757 + 2147386459 = 2147387216
Showing the first eight; more decompositions exist.
