Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629828, here are decompositions:

5 + 8629823 = 8629828
89 + 8629739 = 8629828
149 + 8629679 = 8629828
167 + 8629661 = 8629828
191 + 8629637 = 8629828
419 + 8629409 = 8629828
479 + 8629349 = 8629828
587 + 8629241 = 8629828

Showing the first eight; more decompositions exist.
