Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478972, here are decompositions:

5 + 478967 = 478972
29 + 478943 = 478972
41 + 478931 = 478972
59 + 478913 = 478972
71 + 478901 = 478972
101 + 478871 = 478972
149 + 478823 = 478972
233 + 478739 = 478972

Showing the first eight; more decompositions exist.
