Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584600, here are decompositions:

23 + 31584577 = 31584600
41 + 31584559 = 31584600
53 + 31584547 = 31584600
59 + 31584541 = 31584600
101 + 31584499 = 31584600
193 + 31584407 = 31584600
199 + 31584401 = 31584600
211 + 31584389 = 31584600

Showing the first eight; more decompositions exist.
