Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612436, here are decompositions:

7 + 31612429 = 31612436
13 + 31612423 = 31612436
67 + 31612369 = 31612436
73 + 31612363 = 31612436
127 + 31612309 = 31612436
367 + 31612069 = 31612436
439 + 31611997 = 31612436
607 + 31611829 = 31612436

Showing the first eight; more decompositions exist.
