Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583068, here are decompositions:

17 + 31583051 = 31583068
107 + 31582961 = 31583068
131 + 31582937 = 31583068
137 + 31582931 = 31583068
311 + 31582757 = 31583068
389 + 31582679 = 31583068
401 + 31582667 = 31583068
467 + 31582601 = 31583068

Showing the first eight; more decompositions exist.
