Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613074, here are decompositions:

47 + 31613027 = 31613074
83 + 31612991 = 31613074
113 + 31612961 = 31613074
347 + 31612727 = 31613074
491 + 31612583 = 31613074
587 + 31612487 = 31613074
593 + 31612481 = 31613074
683 + 31612391 = 31613074

Showing the first eight; more decompositions exist.
