Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947810, here are decompositions:

7 + 947803 = 947810
37 + 947773 = 947810
67 + 947743 = 947810
103 + 947707 = 947810
151 + 947659 = 947810
163 + 947647 = 947810
271 + 947539 = 947810
379 + 947431 = 947810

Showing the first eight; more decompositions exist.
