Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147423882, here are decompositions:
- 31 + 2147423851 = 2147423882
- 61 + 2147423821 = 2147423882
- 139 + 2147423743 = 2147423882
- 181 + 2147423701 = 2147423882
- 193 + 2147423689 = 2147423882
- 199 + 2147423683 = 2147423882
- 211 + 2147423671 = 2147423882
- 223 + 2147423659 = 2147423882
Showing the first eight; more decompositions exist.
