Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507764, here are decompositions:

11 + 31507753 = 31507764
61 + 31507703 = 31507764
97 + 31507667 = 31507764
103 + 31507661 = 31507764
131 + 31507633 = 31507764
157 + 31507607 = 31507764
173 + 31507591 = 31507764
181 + 31507583 = 31507764

Showing the first eight; more decompositions exist.
