Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583008, here are decompositions:

47 + 31582961 = 31583008
59 + 31582949 = 31583008
71 + 31582937 = 31583008
101 + 31582907 = 31583008
227 + 31582781 = 31583008
251 + 31582757 = 31583008
269 + 31582739 = 31583008
419 + 31582589 = 31583008

Showing the first eight; more decompositions exist.
