Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555666, here are decompositions:

5 + 33555661 = 33555666
7 + 33555659 = 33555666
19 + 33555647 = 33555666
37 + 33555629 = 33555666
83 + 33555583 = 33555666
103 + 33555563 = 33555666
113 + 33555553 = 33555666
139 + 33555527 = 33555666

Showing the first eight; more decompositions exist.
