Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620946, here are decompositions:

3 + 31620943 = 31620946
107 + 31620839 = 31620946
167 + 31620779 = 31620946
197 + 31620749 = 31620946
263 + 31620683 = 31620946
347 + 31620599 = 31620946
449 + 31620497 = 31620946
503 + 31620443 = 31620946

Showing the first eight; more decompositions exist.
