Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556778, here are decompositions:

67 + 33556711 = 33556778
97 + 33556681 = 33556778
181 + 33556597 = 33556778
271 + 33556507 = 33556778
349 + 33556429 = 33556778
379 + 33556399 = 33556778
397 + 33556381 = 33556778
421 + 33556357 = 33556778

Showing the first eight; more decompositions exist.
