Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478546, here are decompositions:

23 + 478523 = 478546
53 + 478493 = 478546
113 + 478433 = 478546
293 + 478253 = 478546
347 + 478199 = 478546
389 + 478157 = 478546
479 + 478067 = 478546
569 + 477977 = 478546

Showing the first eight; more decompositions exist.
