Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611516, here are decompositions:

7 + 31611509 = 31611516
29 + 31611487 = 31611516
43 + 31611473 = 31611516
59 + 31611457 = 31611516
113 + 31611403 = 31611516
137 + 31611379 = 31611516
149 + 31611367 = 31611516
193 + 31611323 = 31611516

Showing the first eight; more decompositions exist.
