Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472578, here are decompositions:

5 + 472573 = 472578
17 + 472561 = 472578
19 + 472559 = 472578
37 + 472541 = 472578
101 + 472477 = 472578
109 + 472469 = 472578
157 + 472421 = 472578
167 + 472411 = 472578

Showing the first eight; more decompositions exist.
