Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947158, here are decompositions:

29 + 947129 = 947158
131 + 947027 = 947158
197 + 946961 = 947158
227 + 946931 = 947158
239 + 946919 = 947158
257 + 946901 = 947158
281 + 946877 = 947158
389 + 946769 = 947158

Showing the first eight; more decompositions exist.
