Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488582, here are decompositions:

19 + 31488563 = 31488582
89 + 31488493 = 31488582
101 + 31488481 = 31488582
113 + 31488469 = 31488582
149 + 31488433 = 31488582
211 + 31488371 = 31488582
283 + 31488299 = 31488582
311 + 31488271 = 31488582

Showing the first eight; more decompositions exist.
