Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612662, here are decompositions:

41 + 31612621 = 31612662
43 + 31612619 = 31612662
73 + 31612589 = 31612662
79 + 31612583 = 31612662
89 + 31612573 = 31612662
131 + 31612531 = 31612662
149 + 31612513 = 31612662
181 + 31612481 = 31612662

Showing the first eight; more decompositions exist.
