Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478748, here are decompositions:

7 + 478741 = 478748
19 + 478729 = 478748
37 + 478711 = 478748
97 + 478651 = 478748
307 + 478441 = 478748
331 + 478417 = 478748
337 + 478411 = 478748
349 + 478399 = 478748

Showing the first eight; more decompositions exist.
