Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628844, here are decompositions:

53 + 8628791 = 8628844
71 + 8628773 = 8628844
167 + 8628677 = 8628844
197 + 8628647 = 8628844
293 + 8628551 = 8628844
401 + 8628443 = 8628844
461 + 8628383 = 8628844
467 + 8628377 = 8628844

Showing the first eight; more decompositions exist.
