Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947138, here are decompositions:

19 + 947119 = 947138
151 + 946987 = 947138
277 + 946861 = 947138
337 + 946801 = 947138
397 + 946741 = 947138
421 + 946717 = 947138
457 + 946681 = 947138
631 + 946507 = 947138

Showing the first eight; more decompositions exist.
