Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611754, here are decompositions:

17 + 31611737 = 31611754
107 + 31611647 = 31611754
113 + 31611641 = 31611754
137 + 31611617 = 31611754
173 + 31611581 = 31611754
227 + 31611527 = 31611754
281 + 31611473 = 31611754
431 + 31611323 = 31611754

Showing the first eight; more decompositions exist.
