Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478172, here are decompositions:

3 + 478169 = 478172
43 + 478129 = 478172
61 + 478111 = 478172
73 + 478099 = 478172
103 + 478069 = 478172
109 + 478063 = 478172
181 + 477991 = 478172
199 + 477973 = 478172

Showing the first eight; more decompositions exist.
