Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947148, here are decompositions:

11 + 947137 = 947148
19 + 947129 = 947148
29 + 947119 = 947148
151 + 946997 = 947148
179 + 946969 = 947148
199 + 946949 = 947148
229 + 946919 = 947148
271 + 946877 = 947148

Showing the first eight; more decompositions exist.
