Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534722, here are decompositions:

13 + 31534709 = 31534722
31 + 31534691 = 31534722
53 + 31534669 = 31534722
71 + 31534651 = 31534722
179 + 31534543 = 31534722
229 + 31534493 = 31534722
239 + 31534483 = 31534722
281 + 31534441 = 31534722

Showing the first eight; more decompositions exist.
