Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478564, here are decompositions:

41 + 478523 = 478564
71 + 478493 = 478564
83 + 478481 = 478564
113 + 478451 = 478564
131 + 478433 = 478564
137 + 478427 = 478564
173 + 478391 = 478564
293 + 478271 = 478564

Showing the first eight; more decompositions exist.
