Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601044, here are decompositions:

3 + 31601041 = 31601044
227 + 31600817 = 31601044
311 + 31600733 = 31601044
521 + 31600523 = 31601044
593 + 31600451 = 31601044
743 + 31600301 = 31601044
887 + 31600157 = 31601044
911 + 31600133 = 31601044

Showing the first eight; more decompositions exist.
