Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478130, here are decompositions:

3 + 33478127 = 33478130
19 + 33478111 = 33478130
67 + 33478063 = 33478130
199 + 33477931 = 33478130
313 + 33477817 = 33478130
337 + 33477793 = 33478130
487 + 33477643 = 33478130
571 + 33477559 = 33478130

Showing the first eight; more decompositions exist.
