Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478992, here are decompositions:

29 + 478963 = 478992
61 + 478931 = 478992
79 + 478913 = 478992
113 + 478879 = 478992
131 + 478861 = 478992
139 + 478853 = 478992
149 + 478843 = 478992
179 + 478813 = 478992

Showing the first eight; more decompositions exist.
