Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478122, here are decompositions:

11 + 478111 = 478122
23 + 478099 = 478122
53 + 478069 = 478122
59 + 478063 = 478122
83 + 478039 = 478122
131 + 477991 = 478122
149 + 477973 = 478122
181 + 477941 = 478122

Showing the first eight; more decompositions exist.
