Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728324, here are decompositions:

83 + 8728241 = 8728324
113 + 8728211 = 8728324
131 + 8728193 = 8728324
251 + 8728073 = 8728324
467 + 8727857 = 8728324
557 + 8727767 = 8728324
593 + 8727731 = 8728324
701 + 8727623 = 8728324

Showing the first eight; more decompositions exist.
