Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33577778, here are decompositions:

61 + 33577717 = 33577778
127 + 33577651 = 33577778
277 + 33577501 = 33577778
349 + 33577429 = 33577778
397 + 33577381 = 33577778
439 + 33577339 = 33577778
457 + 33577321 = 33577778
571 + 33577207 = 33577778

Showing the first eight; more decompositions exist.
