Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33577780, here are decompositions:

53 + 33577727 = 33577780
59 + 33577721 = 33577780
233 + 33577547 = 33577780
251 + 33577529 = 33577780
263 + 33577517 = 33577780
479 + 33577301 = 33577780
491 + 33577289 = 33577780
503 + 33577277 = 33577780

Showing the first eight; more decompositions exist.
