Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520676, here are decompositions:

17 + 31520659 = 31520676
59 + 31520617 = 31520676
97 + 31520579 = 31520676
107 + 31520569 = 31520676
139 + 31520537 = 31520676
149 + 31520527 = 31520676
157 + 31520519 = 31520676
167 + 31520509 = 31520676

Showing the first eight; more decompositions exist.
