Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612392, here are decompositions:

11 + 31612381 = 31612392
23 + 31612369 = 31612392
29 + 31612363 = 31612392
41 + 31612351 = 31612392
79 + 31612313 = 31612392
83 + 31612309 = 31612392
151 + 31612241 = 31612392
191 + 31612201 = 31612392

Showing the first eight; more decompositions exist.
