Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507674, here are decompositions:

7 + 31507667 = 31507674
13 + 31507661 = 31507674
41 + 31507633 = 31507674
67 + 31507607 = 31507674
83 + 31507591 = 31507674
97 + 31507577 = 31507674
101 + 31507573 = 31507674
103 + 31507571 = 31507674

Showing the first eight; more decompositions exist.
