Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447096, here are decompositions:

17 + 31447079 = 31447096
53 + 31447043 = 31447096
113 + 31446983 = 31447096
179 + 31446917 = 31447096
257 + 31446839 = 31447096
347 + 31446749 = 31447096
353 + 31446743 = 31447096
503 + 31446593 = 31447096

Showing the first eight; more decompositions exist.
