Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611596, here are decompositions:

13 + 31611583 = 31611596
19 + 31611577 = 31611596
43 + 31611553 = 31611596
109 + 31611487 = 31611596
139 + 31611457 = 31611596
157 + 31611439 = 31611596
193 + 31611403 = 31611596
229 + 31611367 = 31611596

Showing the first eight; more decompositions exist.
