Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478538, here are decompositions:

7 + 478531 = 478538
79 + 478459 = 478538
97 + 478441 = 478538
127 + 478411 = 478538
139 + 478399 = 478538
199 + 478339 = 478538
331 + 478207 = 478538
349 + 478189 = 478538

Showing the first eight; more decompositions exist.
