Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947230, here are decompositions:

47 + 947183 = 947230
59 + 947171 = 947230
101 + 947129 = 947230
197 + 947033 = 947230
233 + 946997 = 947230
269 + 946961 = 947230
281 + 946949 = 947230
311 + 946919 = 947230

Showing the first eight; more decompositions exist.
