Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478538, here are decompositions:

7 + 33478531 = 33478538
61 + 33478477 = 33478538
127 + 33478411 = 33478538
151 + 33478387 = 33478538
307 + 33478231 = 33478538
337 + 33478201 = 33478538
349 + 33478189 = 33478538
607 + 33477931 = 33478538

Showing the first eight; more decompositions exist.
