Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478138, here are decompositions:

11 + 33478127 = 33478138
17 + 33478121 = 33478138
41 + 33478097 = 33478138
59 + 33478079 = 33478138
137 + 33478001 = 33478138
167 + 33477971 = 33478138
257 + 33477881 = 33478138
479 + 33477659 = 33478138

Showing the first eight; more decompositions exist.
