Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947072, here are decompositions:

79 + 946993 = 947072
103 + 946969 = 947072
199 + 946873 = 947072
211 + 946861 = 947072
271 + 946801 = 947072
331 + 946741 = 947072
409 + 946663 = 947072
499 + 946573 = 947072

Showing the first eight; more decompositions exist.
