Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611700, here are decompositions:

41 + 31611659 = 31611700
53 + 31611647 = 31611700
59 + 31611641 = 31611700
83 + 31611617 = 31611700
173 + 31611527 = 31611700
191 + 31611509 = 31611700
227 + 31611473 = 31611700
233 + 31611467 = 31611700

Showing the first eight; more decompositions exist.
