Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478508, here are decompositions:

67 + 478441 = 478508
97 + 478411 = 478508
109 + 478399 = 478508
157 + 478351 = 478508
337 + 478171 = 478508
379 + 478129 = 478508
397 + 478111 = 478508
409 + 478099 = 478508

Showing the first eight; more decompositions exist.
