Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584654, here are decompositions:

37 + 31584617 = 31584654
41 + 31584613 = 31584654
47 + 31584607 = 31584654
53 + 31584601 = 31584654
103 + 31584551 = 31584654
107 + 31584547 = 31584654
113 + 31584541 = 31584654
131 + 31584523 = 31584654

Showing the first eight; more decompositions exist.
