Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507714, here are decompositions:

5 + 31507709 = 31507714
11 + 31507703 = 31507714
47 + 31507667 = 31507714
53 + 31507661 = 31507714
107 + 31507607 = 31507714
131 + 31507583 = 31507714
137 + 31507577 = 31507714
191 + 31507523 = 31507714

Showing the first eight; more decompositions exist.
