Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478902, here are decompositions:

5 + 478897 = 478902
23 + 478879 = 478902
31 + 478871 = 478902
41 + 478861 = 478902
59 + 478843 = 478902
71 + 478831 = 478902
79 + 478823 = 478902
89 + 478813 = 478902

Showing the first eight; more decompositions exist.
