Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584862, here are decompositions:

53 + 31584809 = 31584862
149 + 31584713 = 31584862
173 + 31584689 = 31584862
311 + 31584551 = 31584862
431 + 31584431 = 31584862
461 + 31584401 = 31584862
479 + 31584383 = 31584862
563 + 31584299 = 31584862

Showing the first eight; more decompositions exist.
