Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627294, here are decompositions:

5 + 31627289 = 31627294
47 + 31627247 = 31627294
173 + 31627121 = 31627294
317 + 31626977 = 31627294
401 + 31626893 = 31627294
467 + 31626827 = 31627294
761 + 31626533 = 31627294
857 + 31626437 = 31627294

Showing the first eight; more decompositions exist.
