Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470278, here are decompositions:

59 + 470219 = 470278
71 + 470207 = 470278
191 + 470087 = 470278
197 + 470081 = 470278
239 + 470039 = 470278
257 + 470021 = 470278
359 + 469919 = 470278
401 + 469877 = 470278

Showing the first eight; more decompositions exist.
