Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507704, here are decompositions:

5 + 31507699 = 31507704
37 + 31507667 = 31507704
43 + 31507661 = 31507704
71 + 31507633 = 31507704
97 + 31507607 = 31507704
113 + 31507591 = 31507704
127 + 31507577 = 31507704
131 + 31507573 = 31507704

Showing the first eight; more decompositions exist.
