Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472988, here are decompositions:

67 + 472921 = 472988
79 + 472909 = 472988
151 + 472837 = 472988
157 + 472831 = 472988
277 + 472711 = 472988
349 + 472639 = 472988
577 + 472411 = 472988
619 + 472369 = 472988

Showing the first eight; more decompositions exist.
