Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620658, here are decompositions:

59 + 31620599 = 31620658
89 + 31620569 = 31620658
137 + 31620521 = 31620658
227 + 31620431 = 31620658
359 + 31620299 = 31620658
389 + 31620269 = 31620658
449 + 31620209 = 31620658
467 + 31620191 = 31620658

Showing the first eight; more decompositions exist.
