Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947180, here are decompositions:

43 + 947137 = 947180
61 + 947119 = 947180
97 + 947083 = 947180
193 + 946987 = 947180
211 + 946969 = 947180
307 + 946873 = 947180
379 + 946801 = 947180
397 + 946783 = 947180

Showing the first eight; more decompositions exist.
