Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613236, here are decompositions:

383 + 31612853 = 31613236
503 + 31612733 = 31613236
509 + 31612727 = 31613236
569 + 31612667 = 31613236
617 + 31612619 = 31613236
647 + 31612589 = 31613236
653 + 31612583 = 31613236
929 + 31612307 = 31613236

Showing the first eight; more decompositions exist.
