Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470796, here are decompositions:

3 + 31470793 = 31470796
167 + 31470629 = 31470796
173 + 31470623 = 31470796
233 + 31470563 = 31470796
239 + 31470557 = 31470796
353 + 31470443 = 31470796
443 + 31470353 = 31470796
503 + 31470293 = 31470796

Showing the first eight; more decompositions exist.
