Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478142, here are decompositions:

31 + 33478111 = 33478142
79 + 33478063 = 33478142
211 + 33477931 = 33478142
349 + 33477793 = 33478142
463 + 33477679 = 33478142
499 + 33477643 = 33478142
619 + 33477523 = 33478142
661 + 33477481 = 33478142

Showing the first eight; more decompositions exist.
