Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477720, here are decompositions:

7 + 33477713 = 33477720
37 + 33477683 = 33477720
41 + 33477679 = 33477720
61 + 33477659 = 33477720
71 + 33477649 = 33477720
167 + 33477553 = 33477720
193 + 33477527 = 33477720
197 + 33477523 = 33477720

Showing the first eight; more decompositions exist.
