Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478460, here are decompositions:

7 + 478453 = 478460
19 + 478441 = 478460
43 + 478417 = 478460
61 + 478399 = 478460
109 + 478351 = 478460
139 + 478321 = 478460
271 + 478189 = 478460
331 + 478129 = 478460

Showing the first eight; more decompositions exist.
