Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507296, here are decompositions:

13 + 31507283 = 31507296
53 + 31507243 = 31507296
97 + 31507199 = 31507296
137 + 31507159 = 31507296
157 + 31507139 = 31507296
179 + 31507117 = 31507296
347 + 31506949 = 31507296
367 + 31506929 = 31507296

Showing the first eight; more decompositions exist.
