Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612502, here are decompositions:

73 + 31612429 = 31612502
79 + 31612423 = 31612502
139 + 31612363 = 31612502
151 + 31612351 = 31612502
193 + 31612309 = 31612502
421 + 31612081 = 31612502
433 + 31612069 = 31612502
619 + 31611883 = 31612502

Showing the first eight; more decompositions exist.
