Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620932, here are decompositions:

61 + 31620871 = 31620932
139 + 31620793 = 31620932
181 + 31620751 = 31620932
199 + 31620733 = 31620932
223 + 31620709 = 31620932
271 + 31620661 = 31620932
331 + 31620601 = 31620932
433 + 31620499 = 31620932

Showing the first eight; more decompositions exist.
