Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478180, here are decompositions:

3 + 33478177 = 33478180
11 + 33478169 = 33478180
17 + 33478163 = 33478180
53 + 33478127 = 33478180
59 + 33478121 = 33478180
83 + 33478097 = 33478180
101 + 33478079 = 33478180
167 + 33478013 = 33478180

Showing the first eight; more decompositions exist.
