Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476896, here are decompositions:

43 + 31476853 = 31476896
67 + 31476829 = 31476896
97 + 31476799 = 31476896
163 + 31476733 = 31476896
193 + 31476703 = 31476896
349 + 31476547 = 31476896
379 + 31476517 = 31476896
397 + 31476499 = 31476896

Showing the first eight; more decompositions exist.
