Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507176, here are decompositions:

17 + 31507159 = 31507176
37 + 31507139 = 31507176
59 + 31507117 = 31507176
67 + 31507109 = 31507176
89 + 31507087 = 31507176
139 + 31507037 = 31507176
167 + 31507009 = 31507176
199 + 31506977 = 31507176

Showing the first eight; more decompositions exist.
