Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522630, here are decompositions:

17 + 31522613 = 31522630
47 + 31522583 = 31522630
89 + 31522541 = 31522630
101 + 31522529 = 31522630
107 + 31522523 = 31522630
137 + 31522493 = 31522630
179 + 31522451 = 31522630
197 + 31522433 = 31522630

Showing the first eight; more decompositions exist.
