Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523044, here are decompositions:

17 + 31523027 = 31523044
23 + 31523021 = 31523044
41 + 31523003 = 31523044
83 + 31522961 = 31523044
107 + 31522937 = 31523044
197 + 31522847 = 31523044
431 + 31522613 = 31523044
461 + 31522583 = 31523044

Showing the first eight; more decompositions exist.
