Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537782, here are decompositions:

41 + 31537741 = 31537782
61 + 31537721 = 31537782
151 + 31537631 = 31537782
173 + 31537609 = 31537782
179 + 31537603 = 31537782
191 + 31537591 = 31537782
223 + 31537559 = 31537782
239 + 31537543 = 31537782

Showing the first eight; more decompositions exist.
