Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620852, here are decompositions:

13 + 31620839 = 31620852
31 + 31620821 = 31620852
59 + 31620793 = 31620852
73 + 31620779 = 31620852
89 + 31620763 = 31620852
101 + 31620751 = 31620852
103 + 31620749 = 31620852
173 + 31620679 = 31620852

Showing the first eight; more decompositions exist.
