Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33558878, here are decompositions:

37 + 33558841 = 33558878
127 + 33558751 = 33558878
229 + 33558649 = 33558878
421 + 33558457 = 33558878
439 + 33558439 = 33558878
607 + 33558271 = 33558878
631 + 33558247 = 33558878
811 + 33558067 = 33558878

Showing the first eight; more decompositions exist.
