Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725770, here are decompositions:

13 + 8725757 = 8725770
37 + 8725733 = 8725770
71 + 8725699 = 8725770
89 + 8725681 = 8725770
101 + 8725669 = 8725770
113 + 8725657 = 8725770
127 + 8725643 = 8725770
139 + 8725631 = 8725770

Showing the first eight; more decompositions exist.
