Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478442, here are decompositions:

31 + 478411 = 478442
43 + 478399 = 478442
103 + 478339 = 478442
199 + 478243 = 478442
229 + 478213 = 478442
271 + 478171 = 478442
313 + 478129 = 478442
331 + 478111 = 478442

Showing the first eight; more decompositions exist.
