Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612734, here are decompositions:

5 + 31612729 = 31612734
7 + 31612727 = 31612734
67 + 31612667 = 31612734
71 + 31612663 = 31612734
73 + 31612661 = 31612734
107 + 31612627 = 31612734
113 + 31612621 = 31612734
137 + 31612597 = 31612734

Showing the first eight; more decompositions exist.
