Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612692, here are decompositions:

29 + 31612663 = 31612692
31 + 31612661 = 31612692
71 + 31612621 = 31612692
73 + 31612619 = 31612692
103 + 31612589 = 31612692
109 + 31612583 = 31612692
179 + 31612513 = 31612692
211 + 31612481 = 31612692

Showing the first eight; more decompositions exist.
