Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507110, here are decompositions:

23 + 31507087 = 31507110
29 + 31507081 = 31507110
73 + 31507037 = 31507110
101 + 31507009 = 31507110
137 + 31506973 = 31507110
179 + 31506931 = 31507110
181 + 31506929 = 31507110
199 + 31506911 = 31507110

Showing the first eight; more decompositions exist.
