Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537722, here are decompositions:

5 + 31537717 = 31537722
31 + 31537691 = 31537722
113 + 31537609 = 31537722
131 + 31537591 = 31537722
149 + 31537573 = 31537722
163 + 31537559 = 31537722
179 + 31537543 = 31537722
241 + 31537481 = 31537722

Showing the first eight; more decompositions exist.
