Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470376, here are decompositions:

17 + 31470359 = 31470376
23 + 31470353 = 31470376
53 + 31470323 = 31470376
83 + 31470293 = 31470376
167 + 31470209 = 31470376
233 + 31470143 = 31470376
389 + 31469987 = 31470376
563 + 31469813 = 31470376

Showing the first eight; more decompositions exist.
