Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601082, here are decompositions:

5 + 31601077 = 31601082
31 + 31601051 = 31601082
41 + 31601041 = 31601082
59 + 31601023 = 31601082
89 + 31600993 = 31601082
113 + 31600969 = 31601082
199 + 31600883 = 31601082
223 + 31600859 = 31601082

Showing the first eight; more decompositions exist.
