Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947822, here are decompositions:

3 + 947819 = 947822
19 + 947803 = 947822
79 + 947743 = 947822
103 + 947719 = 947822
163 + 947659 = 947822
181 + 947641 = 947822
283 + 947539 = 947822
313 + 947509 = 947822

Showing the first eight; more decompositions exist.
