Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612374, here are decompositions:

5 + 31612369 = 31612374
11 + 31612363 = 31612374
23 + 31612351 = 31612374
61 + 31612313 = 31612374
67 + 31612307 = 31612374
97 + 31612277 = 31612374
151 + 31612223 = 31612374
173 + 31612201 = 31612374

Showing the first eight; more decompositions exist.
