Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611702, here are decompositions:

29 + 31611673 = 31611702
43 + 31611659 = 31611702
61 + 31611641 = 31611702
149 + 31611553 = 31611702
163 + 31611539 = 31611702
193 + 31611509 = 31611702
229 + 31611473 = 31611702
263 + 31611439 = 31611702

Showing the first eight; more decompositions exist.
