Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583010, here are decompositions:

29 + 31582981 = 31583010
59 + 31582951 = 31583010
61 + 31582949 = 31583010
73 + 31582937 = 31583010
79 + 31582931 = 31583010
97 + 31582913 = 31583010
103 + 31582907 = 31583010
113 + 31582897 = 31583010

Showing the first eight; more decompositions exist.
