Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537626, here are decompositions:

17 + 31537609 = 31537626
23 + 31537603 = 31537626
53 + 31537573 = 31537626
67 + 31537559 = 31537626
79 + 31537547 = 31537626
83 + 31537543 = 31537626
149 + 31537477 = 31537626
157 + 31537469 = 31537626

Showing the first eight; more decompositions exist.
