Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590766, here are decompositions:

3 + 31590763 = 31590766
29 + 31590737 = 31590766
83 + 31590683 = 31590766
107 + 31590659 = 31590766
149 + 31590617 = 31590766
173 + 31590593 = 31590766
353 + 31590413 = 31590766
503 + 31590263 = 31590766

Showing the first eight; more decompositions exist.
