Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613906, here are decompositions:

67 + 31613839 = 31613906
73 + 31613833 = 31613906
109 + 31613797 = 31613906
277 + 31613629 = 31613906
283 + 31613623 = 31613906
367 + 31613539 = 31613906
523 + 31613383 = 31613906
769 + 31613137 = 31613906

Showing the first eight; more decompositions exist.
