Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947686, here are decompositions:

59 + 947627 = 947686
83 + 947603 = 947686
107 + 947579 = 947686
263 + 947423 = 947686
269 + 947417 = 947686
317 + 947369 = 947686
359 + 947327 = 947686
503 + 947183 = 947686

Showing the first eight; more decompositions exist.
