Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947240, here are decompositions:

37 + 947203 = 947240
43 + 947197 = 947240
103 + 947137 = 947240
157 + 947083 = 947240
271 + 946969 = 947240
367 + 946873 = 947240
379 + 946861 = 947240
421 + 946819 = 947240

Showing the first eight; more decompositions exist.
