Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472130, here are decompositions:

3 + 472127 = 472130
7 + 472123 = 472130
19 + 472111 = 472130
67 + 472063 = 472130
73 + 472057 = 472130
79 + 472051 = 472130
103 + 472027 = 472130
181 + 471949 = 472130

Showing the first eight; more decompositions exist.
