Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478988, here are decompositions:

61 + 478927 = 478988
109 + 478879 = 478988
127 + 478861 = 478988
157 + 478831 = 478988
241 + 478747 = 478988
277 + 478711 = 478988
337 + 478651 = 478988
409 + 478579 = 478988

Showing the first eight; more decompositions exist.
