Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478478, here are decompositions:

67 + 33478411 = 33478478
277 + 33478201 = 33478478
367 + 33478111 = 33478478
547 + 33477931 = 33478478
661 + 33477817 = 33478478
829 + 33477649 = 33478478
919 + 33477559 = 33478478
997 + 33477481 = 33478478

Showing the first eight; more decompositions exist.
