Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947838, here are decompositions:

5 + 947833 = 947838
19 + 947819 = 947838
97 + 947741 = 947838
109 + 947729 = 947838
127 + 947711 = 947838
131 + 947707 = 947838
179 + 947659 = 947838
191 + 947647 = 947838

Showing the first eight; more decompositions exist.
