Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537698, here are decompositions:

7 + 31537691 = 31537698
11 + 31537687 = 31537698
67 + 31537631 = 31537698
89 + 31537609 = 31537698
107 + 31537591 = 31537698
139 + 31537559 = 31537698
151 + 31537547 = 31537698
191 + 31537507 = 31537698

Showing the first eight; more decompositions exist.
