Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447246, here are decompositions:

29 + 31447217 = 31447246
113 + 31447133 = 31447246
167 + 31447079 = 31447246
227 + 31447019 = 31447246
263 + 31446983 = 31447246
293 + 31446953 = 31447246
353 + 31446893 = 31447246
503 + 31446743 = 31447246

Showing the first eight; more decompositions exist.
