Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611546, here are decompositions:

7 + 31611539 = 31611546
19 + 31611527 = 31611546
37 + 31611509 = 31611546
59 + 31611487 = 31611546
73 + 31611473 = 31611546
79 + 31611467 = 31611546
89 + 31611457 = 31611546
107 + 31611439 = 31611546

Showing the first eight; more decompositions exist.
