Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612382, here are decompositions:

13 + 31612369 = 31612382
19 + 31612363 = 31612382
31 + 31612351 = 31612382
73 + 31612309 = 31612382
181 + 31612201 = 31612382
313 + 31612069 = 31612382
499 + 31611883 = 31612382
541 + 31611841 = 31612382

Showing the first eight; more decompositions exist.
