Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478530, here are decompositions:

13 + 33478517 = 33478530
53 + 33478477 = 33478530
61 + 33478469 = 33478530
97 + 33478433 = 33478530
109 + 33478421 = 33478530
139 + 33478391 = 33478530
193 + 33478337 = 33478530
199 + 33478331 = 33478530

Showing the first eight; more decompositions exist.
