Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947144, here are decompositions:

7 + 947137 = 947144
61 + 947083 = 947144
151 + 946993 = 947144
157 + 946987 = 947144
271 + 946873 = 947144
283 + 946861 = 947144
463 + 946681 = 947144
571 + 946573 = 947144

Showing the first eight; more decompositions exist.
