Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478690, here are decompositions:

41 + 33478649 = 33478690
83 + 33478607 = 33478690
107 + 33478583 = 33478690
173 + 33478517 = 33478690
251 + 33478439 = 33478690
257 + 33478433 = 33478690
269 + 33478421 = 33478690
353 + 33478337 = 33478690

Showing the first eight; more decompositions exist.
