Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514560, here are decompositions:

23 + 31514537 = 31514560
47 + 31514513 = 31514560
83 + 31514477 = 31514560
131 + 31514429 = 31514560
137 + 31514423 = 31514560
251 + 31514309 = 31514560
263 + 31514297 = 31514560
269 + 31514291 = 31514560

Showing the first eight; more decompositions exist.
