Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478042, here are decompositions:

3 + 478039 = 478042
41 + 478001 = 478042
101 + 477941 = 478042
179 + 477863 = 478042
233 + 477809 = 478042
251 + 477791 = 478042
311 + 477731 = 478042
419 + 477623 = 478042

Showing the first eight; more decompositions exist.
