Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478100, here are decompositions:

3 + 33478097 = 33478100
37 + 33478063 = 33478100
283 + 33477817 = 33478100
307 + 33477793 = 33478100
421 + 33477679 = 33478100
457 + 33477643 = 33478100
541 + 33477559 = 33478100
547 + 33477553 = 33478100

Showing the first eight; more decompositions exist.
