Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612466, here are decompositions:

13 + 31612453 = 31612466
37 + 31612429 = 31612466
43 + 31612423 = 31612466
97 + 31612369 = 31612466
103 + 31612363 = 31612466
157 + 31612309 = 31612466
397 + 31612069 = 31612466
709 + 31611757 = 31612466

Showing the first eight; more decompositions exist.
