Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507004, here are decompositions:

31 + 31506973 = 31507004
73 + 31506931 = 31507004
97 + 31506907 = 31507004
163 + 31506841 = 31507004
181 + 31506823 = 31507004
211 + 31506793 = 31507004
223 + 31506781 = 31507004
307 + 31506697 = 31507004

Showing the first eight; more decompositions exist.
