Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583060, here are decompositions:

13 + 31583047 = 31583060
37 + 31583023 = 31583060
79 + 31582981 = 31583060
109 + 31582951 = 31583060
163 + 31582897 = 31583060
241 + 31582819 = 31583060
283 + 31582777 = 31583060
331 + 31582729 = 31583060

Showing the first eight; more decompositions exist.
