Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620376, here are decompositions:

17 + 31620359 = 31620376
59 + 31620317 = 31620376
107 + 31620269 = 31620376
113 + 31620263 = 31620376
167 + 31620209 = 31620376
173 + 31620203 = 31620376
269 + 31620107 = 31620376
317 + 31620059 = 31620376

Showing the first eight; more decompositions exist.
