Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478228, here are decompositions:

29 + 33478199 = 33478228
59 + 33478169 = 33478228
101 + 33478127 = 33478228
107 + 33478121 = 33478228
131 + 33478097 = 33478228
149 + 33478079 = 33478228
167 + 33478061 = 33478228
227 + 33478001 = 33478228

Showing the first eight; more decompositions exist.
