Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947530, here are decompositions:

29 + 947501 = 947530
47 + 947483 = 947530
107 + 947423 = 947530
113 + 947417 = 947530
149 + 947381 = 947530
173 + 947357 = 947530
179 + 947351 = 947530
347 + 947183 = 947530

Showing the first eight; more decompositions exist.
