Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33607780, here are decompositions:

47 + 33607733 = 33607780
53 + 33607727 = 33607780
83 + 33607697 = 33607780
233 + 33607547 = 33607780
251 + 33607529 = 33607780
359 + 33607421 = 33607780
389 + 33607391 = 33607780
431 + 33607349 = 33607780

Showing the first eight; more decompositions exist.
