Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476766, here are decompositions:

23 + 31476743 = 31476766
173 + 31476593 = 31476766
179 + 31476587 = 31476766
257 + 31476509 = 31476766
317 + 31476449 = 31476766
353 + 31476413 = 31476766
383 + 31476383 = 31476766
449 + 31476317 = 31476766

Showing the first eight; more decompositions exist.
