Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620676, here are decompositions:

107 + 31620569 = 31620676
179 + 31620497 = 31620676
233 + 31620443 = 31620676
317 + 31620359 = 31620676
359 + 31620317 = 31620676
467 + 31620209 = 31620676
509 + 31620167 = 31620676
569 + 31620107 = 31620676

Showing the first eight; more decompositions exist.
