Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583582, here are decompositions:

61 + 31583521 = 31583582
73 + 31583509 = 31583582
229 + 31583353 = 31583582
313 + 31583269 = 31583582
601 + 31582981 = 31583582
631 + 31582951 = 31583582
691 + 31582891 = 31583582
853 + 31582729 = 31583582

Showing the first eight; more decompositions exist.
