Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522470, here are decompositions:

11 + 31522459 = 31522470
19 + 31522451 = 31522470
29 + 31522441 = 31522470
37 + 31522433 = 31522470
59 + 31522411 = 31522470
97 + 31522373 = 31522470
107 + 31522363 = 31522470
113 + 31522357 = 31522470

Showing the first eight; more decompositions exist.
