Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556978, here are decompositions:

17 + 33556961 = 33556978
41 + 33556937 = 33556978
89 + 33556889 = 33556978
101 + 33556877 = 33556978
131 + 33556847 = 33556978
137 + 33556841 = 33556978
167 + 33556811 = 33556978
419 + 33556559 = 33556978

Showing the first eight; more decompositions exist.
