Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590362, here are decompositions:

19 + 31590343 = 31590362
151 + 31590211 = 31590362
229 + 31590133 = 31590362
241 + 31590121 = 31590362
379 + 31589983 = 31590362
409 + 31589953 = 31590362
439 + 31589923 = 31590362
631 + 31589731 = 31590362

Showing the first eight; more decompositions exist.
