Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478238, here are decompositions:

7 + 33478231 = 33478238
37 + 33478201 = 33478238
61 + 33478177 = 33478238
127 + 33478111 = 33478238
229 + 33478009 = 33478238
307 + 33477931 = 33478238
421 + 33477817 = 33478238
757 + 33477481 = 33478238

Showing the first eight; more decompositions exist.
