Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628748, here are decompositions:

71 + 8628677 = 8628748
101 + 8628647 = 8628748
197 + 8628551 = 8628748
269 + 8628479 = 8628748
389 + 8628359 = 8628748
587 + 8628161 = 8628748
599 + 8628149 = 8628748
617 + 8628131 = 8628748

Showing the first eight; more decompositions exist.
