Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947988, here are decompositions:

29 + 947959 = 947988
61 + 947927 = 947988
71 + 947917 = 947988
127 + 947861 = 947988
131 + 947857 = 947988
137 + 947851 = 947988
241 + 947747 = 947988
269 + 947719 = 947988

Showing the first eight; more decompositions exist.
