Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33616778, here are decompositions:

67 + 33616711 = 33616778
127 + 33616651 = 33616778
229 + 33616549 = 33616778
271 + 33616507 = 33616778
331 + 33616447 = 33616778
379 + 33616399 = 33616778
397 + 33616381 = 33616778
421 + 33616357 = 33616778

Showing the first eight; more decompositions exist.
