Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625808, here are decompositions:

101 + 8625707 = 8625808
167 + 8625641 = 8625808
281 + 8625527 = 8625808
449 + 8625359 = 8625808
491 + 8625317 = 8625808
617 + 8625191 = 8625808
677 + 8625131 = 8625808
797 + 8625011 = 8625808

Showing the first eight; more decompositions exist.
