Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477390, here are decompositions:

43 + 33477347 = 33477390
53 + 33477337 = 33477390
59 + 33477331 = 33477390
73 + 33477317 = 33477390
83 + 33477307 = 33477390
139 + 33477251 = 33477390
151 + 33477239 = 33477390
179 + 33477211 = 33477390

Showing the first eight; more decompositions exist.
