Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537692, here are decompositions:

5 + 31537687 = 31537692
61 + 31537631 = 31537692
83 + 31537609 = 31537692
89 + 31537603 = 31537692
101 + 31537591 = 31537692
149 + 31537543 = 31537692
211 + 31537481 = 31537692
223 + 31537469 = 31537692

Showing the first eight; more decompositions exist.
