Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947882, here are decompositions:

31 + 947851 = 947882
79 + 947803 = 947882
109 + 947773 = 947882
139 + 947743 = 947882
163 + 947719 = 947882
223 + 947659 = 947882
241 + 947641 = 947882
373 + 947509 = 947882

Showing the first eight; more decompositions exist.
