Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615322, here are decompositions:

283 + 31615039 = 31615322
379 + 31614943 = 31615322
433 + 31614889 = 31615322
463 + 31614859 = 31615322
619 + 31614703 = 31615322
691 + 31614631 = 31615322
829 + 31614493 = 31615322
1039 + 31614283 = 31615322

Showing the first eight; more decompositions exist.
