Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947222, here are decompositions:

19 + 947203 = 947222
103 + 947119 = 947222
139 + 947083 = 947222
229 + 946993 = 947222
349 + 946873 = 947222
421 + 946801 = 947222
439 + 946783 = 947222
541 + 946681 = 947222

Showing the first eight; more decompositions exist.
