Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741728, here are decompositions:

29 + 8741699 = 8741728
41 + 8741687 = 8741728
89 + 8741639 = 8741728
257 + 8741471 = 8741728
269 + 8741459 = 8741728
419 + 8741309 = 8741728
449 + 8741279 = 8741728
587 + 8741141 = 8741728

Showing the first eight; more decompositions exist.
