Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446796, here are decompositions:

47 + 31446749 = 31446796
53 + 31446743 = 31446796
107 + 31446689 = 31446796
233 + 31446563 = 31446796
239 + 31446557 = 31446796
263 + 31446533 = 31446796
467 + 31446329 = 31446796
569 + 31446227 = 31446796

Showing the first eight; more decompositions exist.
