Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507010, here are decompositions:

37 + 31506973 = 31507010
61 + 31506949 = 31507010
79 + 31506931 = 31507010
103 + 31506907 = 31507010
181 + 31506829 = 31507010
211 + 31506799 = 31507010
229 + 31506781 = 31507010
313 + 31506697 = 31507010

Showing the first eight; more decompositions exist.
