Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749320, here are decompositions:

11 + 8749309 = 8749320
101 + 8749219 = 8749320
113 + 8749207 = 8749320
157 + 8749163 = 8749320
179 + 8749141 = 8749320
193 + 8749127 = 8749320
199 + 8749121 = 8749320
233 + 8749087 = 8749320

Showing the first eight; more decompositions exist.
