Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613116, here are decompositions:

89 + 31613027 = 31613116
263 + 31612853 = 31613116
383 + 31612733 = 31613116
389 + 31612727 = 31613116
449 + 31612667 = 31613116
569 + 31612547 = 31613116
809 + 31612307 = 31613116
839 + 31612277 = 31613116

Showing the first eight; more decompositions exist.
