Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947990, here are decompositions:

3 + 947987 = 947990
31 + 947959 = 947990
73 + 947917 = 947990
79 + 947911 = 947990
97 + 947893 = 947990
139 + 947851 = 947990
157 + 947833 = 947990
271 + 947719 = 947990

Showing the first eight; more decompositions exist.
