Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539362, here are decompositions:

13 + 31539349 = 31539362
31 + 31539331 = 31539362
73 + 31539289 = 31539362
79 + 31539283 = 31539362
199 + 31539163 = 31539362
619 + 31538743 = 31539362
643 + 31538719 = 31539362
691 + 31538671 = 31539362

Showing the first eight; more decompositions exist.

IPv4 address
