Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620952, here are decompositions:

5 + 31620947 = 31620952
113 + 31620839 = 31620952
131 + 31620821 = 31620952
173 + 31620779 = 31620952
269 + 31620683 = 31620952
353 + 31620599 = 31620952
383 + 31620569 = 31620952
431 + 31620521 = 31620952

Showing the first eight; more decompositions exist.
