Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725730, here are decompositions:

31 + 8725699 = 8725730
61 + 8725669 = 8725730
73 + 8725657 = 8725730
103 + 8725627 = 8725730
109 + 8725621 = 8725730
163 + 8725567 = 8725730
199 + 8725531 = 8725730
241 + 8725489 = 8725730

Showing the first eight; more decompositions exist.
