Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478718, here are decompositions:

7 + 478711 = 478718
67 + 478651 = 478718
139 + 478579 = 478718
277 + 478441 = 478718
307 + 478411 = 478718
367 + 478351 = 478718
379 + 478339 = 478718
397 + 478321 = 478718

Showing the first eight; more decompositions exist.
