Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583146, here are decompositions:

59 + 31583087 = 31583146
113 + 31583033 = 31583146
197 + 31582949 = 31583146
233 + 31582913 = 31583146
239 + 31582907 = 31583146
389 + 31582757 = 31583146
467 + 31582679 = 31583146
479 + 31582667 = 31583146

Showing the first eight; more decompositions exist.
