Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471388, here are decompositions:

89 + 471299 = 471388
107 + 471281 = 471388
179 + 471209 = 471388
227 + 471161 = 471388
251 + 471137 = 471388
347 + 471041 = 471388
389 + 470999 = 471388
431 + 470957 = 471388

Showing the first eight; more decompositions exist.
