Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522672, here are decompositions:

3 + 31522669 = 31522672
59 + 31522613 = 31522672
89 + 31522583 = 31522672
131 + 31522541 = 31522672
149 + 31522523 = 31522672
179 + 31522493 = 31522672
239 + 31522433 = 31522672
359 + 31522313 = 31522672

Showing the first eight; more decompositions exist.
