Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478268, here are decompositions:

61 + 478207 = 478268
79 + 478189 = 478268
97 + 478171 = 478268
139 + 478129 = 478268
157 + 478111 = 478268
181 + 478087 = 478268
199 + 478069 = 478268
229 + 478039 = 478268

Showing the first eight; more decompositions exist.
