Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33516840, here are decompositions:

47 + 33516793 = 33516840
73 + 33516767 = 33516840
79 + 33516761 = 33516840
89 + 33516751 = 33516840
101 + 33516739 = 33516840
109 + 33516731 = 33516840
151 + 33516689 = 33516840
173 + 33516667 = 33516840

Showing the first eight; more decompositions exist.
