Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590874, here are decompositions:

41 + 31590833 = 31590874
71 + 31590803 = 31590874
83 + 31590791 = 31590874
137 + 31590737 = 31590874
191 + 31590683 = 31590874
257 + 31590617 = 31590874
281 + 31590593 = 31590874
317 + 31590557 = 31590874

Showing the first eight; more decompositions exist.
