Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478166, here are decompositions:

37 + 478129 = 478166
67 + 478099 = 478166
79 + 478087 = 478166
97 + 478069 = 478166
103 + 478063 = 478166
127 + 478039 = 478166
193 + 477973 = 478166
397 + 477769 = 478166

Showing the first eight; more decompositions exist.
