Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507184, here are decompositions:

3 + 31507181 = 31507184
67 + 31507117 = 31507184
97 + 31507087 = 31507184
103 + 31507081 = 31507184
211 + 31506973 = 31507184
277 + 31506907 = 31507184
487 + 31506697 = 31507184
607 + 31506577 = 31507184

Showing the first eight; more decompositions exist.
