Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586032, here are decompositions:

29 + 31586003 = 31586032
53 + 31585979 = 31586032
59 + 31585973 = 31586032
251 + 31585781 = 31586032
281 + 31585751 = 31586032
383 + 31585649 = 31586032
419 + 31585613 = 31586032
449 + 31585583 = 31586032

Showing the first eight; more decompositions exist.
