Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472158, here are decompositions:

7 + 472151 = 472158
19 + 472139 = 472158
31 + 472127 = 472158
47 + 472111 = 472158
101 + 472057 = 472158
107 + 472051 = 472158
131 + 472027 = 472158
139 + 472019 = 472158

Showing the first eight; more decompositions exist.
