Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510534, here are decompositions:

17 + 31510517 = 31510534
47 + 31510487 = 31510534
101 + 31510433 = 31510534
131 + 31510403 = 31510534
137 + 31510397 = 31510534
311 + 31510223 = 31510534
317 + 31510217 = 31510534
347 + 31510187 = 31510534

Showing the first eight; more decompositions exist.
