Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478628, here are decompositions:

97 + 478531 = 478628
211 + 478417 = 478628
229 + 478399 = 478628
277 + 478351 = 478628
307 + 478321 = 478628
421 + 478207 = 478628
439 + 478189 = 478628
457 + 478171 = 478628

Showing the first eight; more decompositions exist.
