Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583422, here are decompositions:

71 + 31583351 = 31583422
251 + 31583171 = 31583422
263 + 31583159 = 31583422
389 + 31583033 = 31583422
461 + 31582961 = 31583422
491 + 31582931 = 31583422
509 + 31582913 = 31583422
599 + 31582823 = 31583422

Showing the first eight; more decompositions exist.
