Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584962, here are decompositions:

61 + 31584901 = 31584962
109 + 31584853 = 31584962
139 + 31584823 = 31584962
193 + 31584769 = 31584962
349 + 31584613 = 31584962
421 + 31584541 = 31584962
439 + 31584523 = 31584962
463 + 31584499 = 31584962

Showing the first eight; more decompositions exist.
