Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522410, here are decompositions:

37 + 31522373 = 31522410
47 + 31522363 = 31522410
53 + 31522357 = 31522410
71 + 31522339 = 31522410
79 + 31522331 = 31522410
83 + 31522327 = 31522410
97 + 31522313 = 31522410
113 + 31522297 = 31522410

Showing the first eight; more decompositions exist.
