Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947228, here are decompositions:

31 + 947197 = 947228
109 + 947119 = 947228
241 + 946987 = 947228
367 + 946861 = 947228
409 + 946819 = 947228
487 + 946741 = 947228
547 + 946681 = 947228
739 + 946489 = 947228

Showing the first eight; more decompositions exist.
