Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539074, here are decompositions:

13 + 31539061 = 31539074
31 + 31539043 = 31539074
67 + 31539007 = 31539074
331 + 31538743 = 31539074
421 + 31538653 = 31539074
433 + 31538641 = 31539074
547 + 31538527 = 31539074
571 + 31538503 = 31539074

Showing the first eight; more decompositions exist.

IPv4 address
