Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33612780, here are decompositions:

17 + 33612763 = 33612780
53 + 33612727 = 33612780
73 + 33612707 = 33612780
79 + 33612701 = 33612780
83 + 33612697 = 33612780
101 + 33612679 = 33612780
107 + 33612673 = 33612780
109 + 33612671 = 33612780

Showing the first eight; more decompositions exist.
