Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620976, here are decompositions:

3 + 31620973 = 31620976
29 + 31620947 = 31620976
137 + 31620839 = 31620976
197 + 31620779 = 31620976
227 + 31620749 = 31620976
239 + 31620737 = 31620976
293 + 31620683 = 31620976
479 + 31620497 = 31620976

Showing the first eight; more decompositions exist.
