Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609012, here are decompositions:

41 + 31608971 = 31609012
53 + 31608959 = 31609012
59 + 31608953 = 31609012
101 + 31608911 = 31609012
191 + 31608821 = 31609012
233 + 31608779 = 31609012
263 + 31608749 = 31609012
563 + 31608449 = 31609012

Showing the first eight; more decompositions exist.
