Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584662, here are decompositions:

61 + 31584601 = 31584662
103 + 31584559 = 31584662
139 + 31584523 = 31584662
163 + 31584499 = 31584662
181 + 31584481 = 31584662
223 + 31584439 = 31584662
523 + 31584139 = 31584662
619 + 31584043 = 31584662

Showing the first eight; more decompositions exist.
