Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478778, here are decompositions:

19 + 33478759 = 33478778
97 + 33478681 = 33478778
127 + 33478651 = 33478778
367 + 33478411 = 33478778
547 + 33478231 = 33478778
577 + 33478201 = 33478778
601 + 33478177 = 33478778
769 + 33478009 = 33478778

Showing the first eight; more decompositions exist.
