Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628478, here are decompositions:

29 + 8628449 = 8628478
71 + 8628407 = 8628478
101 + 8628377 = 8628478
317 + 8628161 = 8628478
347 + 8628131 = 8628478
401 + 8628077 = 8628478
461 + 8628017 = 8628478
491 + 8627987 = 8628478

Showing the first eight; more decompositions exist.
