Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446508, here are decompositions:

17 + 31446491 = 31446508
47 + 31446461 = 31446508
167 + 31446341 = 31446508
179 + 31446329 = 31446508
251 + 31446257 = 31446508
257 + 31446251 = 31446508
281 + 31446227 = 31446508
617 + 31445891 = 31446508

Showing the first eight; more decompositions exist.
