Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555780, here are decompositions:

23 + 33555757 = 33555780
29 + 33555751 = 33555780
43 + 33555737 = 33555780
53 + 33555727 = 33555780
79 + 33555701 = 33555780
101 + 33555679 = 33555780
113 + 33555667 = 33555780
151 + 33555629 = 33555780

Showing the first eight; more decompositions exist.
