Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478186, here are decompositions:

17 + 478169 = 478186
29 + 478157 = 478186
47 + 478139 = 478186
239 + 477947 = 478186
347 + 477839 = 478186
389 + 477797 = 478186
419 + 477767 = 478186
509 + 477677 = 478186

Showing the first eight; more decompositions exist.
