Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615262, here are decompositions:

109 + 31615153 = 31615262
199 + 31615063 = 31615262
223 + 31615039 = 31615262
373 + 31614889 = 31615262
409 + 31614853 = 31615262
433 + 31614829 = 31615262
619 + 31614643 = 31615262
631 + 31614631 = 31615262

Showing the first eight; more decompositions exist.
