Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477578, here are decompositions:

19 + 33477559 = 33477578
61 + 33477517 = 33477578
97 + 33477481 = 33477578
241 + 33477337 = 33477578
271 + 33477307 = 33477578
307 + 33477271 = 33477578
331 + 33477247 = 33477578
367 + 33477211 = 33477578

Showing the first eight; more decompositions exist.
