Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478578, here are decompositions:

17 + 33478561 = 33478578
47 + 33478531 = 33478578
61 + 33478517 = 33478578
101 + 33478477 = 33478578
109 + 33478469 = 33478578
139 + 33478439 = 33478578
157 + 33478421 = 33478578
167 + 33478411 = 33478578

Showing the first eight; more decompositions exist.
