Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611712, here are decompositions:

3 + 31611709 = 31611712
53 + 31611659 = 31611712
71 + 31611641 = 31611712
131 + 31611581 = 31611712
173 + 31611539 = 31611712
239 + 31611473 = 31611712
383 + 31611329 = 31611712
389 + 31611323 = 31611712

Showing the first eight; more decompositions exist.
