Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620862, here are decompositions:

23 + 31620839 = 31620862
41 + 31620821 = 31620862
83 + 31620779 = 31620862
113 + 31620749 = 31620862
179 + 31620683 = 31620862
263 + 31620599 = 31620862
281 + 31620581 = 31620862
293 + 31620569 = 31620862

Showing the first eight; more decompositions exist.
