Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478128, here are decompositions:

17 + 478111 = 478128
29 + 478099 = 478128
41 + 478087 = 478128
59 + 478069 = 478128
61 + 478067 = 478128
89 + 478039 = 478128
127 + 478001 = 478128
137 + 477991 = 478128

Showing the first eight; more decompositions exist.
