Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504044, here are decompositions:

7 + 31504037 = 31504044
31 + 31504013 = 31504044
67 + 31503977 = 31504044
71 + 31503973 = 31504044
73 + 31503971 = 31504044
83 + 31503961 = 31504044
113 + 31503931 = 31504044
127 + 31503917 = 31504044

Showing the first eight; more decompositions exist.
