Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611588, here are decompositions:

5 + 31611583 = 31611588
7 + 31611581 = 31611588
11 + 31611577 = 31611588
61 + 31611527 = 31611588
79 + 31611509 = 31611588
101 + 31611487 = 31611588
131 + 31611457 = 31611588
149 + 31611439 = 31611588

Showing the first eight; more decompositions exist.
