Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620586, here are decompositions:

5 + 31620581 = 31620586
17 + 31620569 = 31620586
89 + 31620497 = 31620586
113 + 31620473 = 31620586
227 + 31620359 = 31620586
269 + 31620317 = 31620586
317 + 31620269 = 31620586
383 + 31620203 = 31620586

Showing the first eight; more decompositions exist.
