Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507098, here are decompositions:

11 + 31507087 = 31507098
17 + 31507081 = 31507098
61 + 31507037 = 31507098
89 + 31507009 = 31507098
149 + 31506949 = 31507098
167 + 31506931 = 31507098
191 + 31506907 = 31507098
211 + 31506887 = 31507098

Showing the first eight; more decompositions exist.
