Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507060, here are decompositions:

23 + 31507037 = 31507060
83 + 31506977 = 31507060
131 + 31506929 = 31507060
149 + 31506911 = 31507060
173 + 31506887 = 31507060
239 + 31506821 = 31507060
251 + 31506809 = 31507060
269 + 31506791 = 31507060

Showing the first eight; more decompositions exist.
