Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629444, here are decompositions:

3 + 8629441 = 8629444
11 + 8629433 = 8629444
101 + 8629343 = 8629444
251 + 8629193 = 8629444
521 + 8628923 = 8629444
587 + 8628857 = 8629444
653 + 8628791 = 8629444
797 + 8628647 = 8629444

Showing the first eight; more decompositions exist.
