Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749224, here are decompositions:

5 + 8749219 = 8749224
17 + 8749207 = 8749224
61 + 8749163 = 8749224
73 + 8749151 = 8749224
83 + 8749141 = 8749224
97 + 8749127 = 8749224
103 + 8749121 = 8749224
137 + 8749087 = 8749224

Showing the first eight; more decompositions exist.
