Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725726, here are decompositions:

83 + 8725643 = 8725726
179 + 8725547 = 8725726
227 + 8725499 = 8725726
263 + 8725463 = 8725726
419 + 8725307 = 8725726
509 + 8725217 = 8725726
587 + 8725139 = 8725726
593 + 8725133 = 8725726

Showing the first eight; more decompositions exist.
