Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611482, here are decompositions:

43 + 31611439 = 31611482
79 + 31611403 = 31611482
103 + 31611379 = 31611482
163 + 31611319 = 31611482
181 + 31611301 = 31611482
211 + 31611271 = 31611482
433 + 31611049 = 31611482
439 + 31611043 = 31611482

Showing the first eight; more decompositions exist.
