Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477990, here are decompositions:

19 + 33477971 = 33477990
59 + 33477931 = 33477990
61 + 33477929 = 33477990
107 + 33477883 = 33477990
109 + 33477881 = 33477990
173 + 33477817 = 33477990
197 + 33477793 = 33477990
277 + 33477713 = 33477990

Showing the first eight; more decompositions exist.
