Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947840, here are decompositions:

7 + 947833 = 947840
37 + 947803 = 947840
67 + 947773 = 947840
97 + 947743 = 947840
181 + 947659 = 947840
193 + 947647 = 947840
199 + 947641 = 947840
331 + 947509 = 947840

Showing the first eight; more decompositions exist.
