Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612262, here are decompositions:

61 + 31612201 = 31612262
181 + 31612081 = 31612262
193 + 31612069 = 31612262
379 + 31611883 = 31612262
421 + 31611841 = 31612262
433 + 31611829 = 31612262
709 + 31611553 = 31612262
823 + 31611439 = 31612262

Showing the first eight; more decompositions exist.
