Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425846, here are decompositions:
- 239 + 2147425607 = 2147425846
- 389 + 2147425457 = 2147425846
- 563 + 2147425283 = 2147425846
- 659 + 2147425187 = 2147425846
- 677 + 2147425169 = 2147425846
- 719 + 2147425127 = 2147425846
- 743 + 2147425103 = 2147425846
- 773 + 2147425073 = 2147425846
Showing the first eight; more decompositions exist.
