Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612358, here are decompositions:

7 + 31612351 = 31612358
157 + 31612201 = 31612358
277 + 31612081 = 31612358
541 + 31611817 = 31612358
601 + 31611757 = 31612358
691 + 31611667 = 31612358
751 + 31611607 = 31612358
919 + 31611439 = 31612358

Showing the first eight; more decompositions exist.
