Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611498, here are decompositions:

11 + 31611487 = 31611498
31 + 31611467 = 31611498
41 + 31611457 = 31611498
59 + 31611439 = 31611498
131 + 31611367 = 31611498
157 + 31611341 = 31611498
179 + 31611319 = 31611498
197 + 31611301 = 31611498

Showing the first eight; more decompositions exist.
