Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749550, here are decompositions:

127 + 8749423 = 8749550
193 + 8749357 = 8749550
241 + 8749309 = 8749550
307 + 8749243 = 8749550
331 + 8749219 = 8749550
409 + 8749141 = 8749550
463 + 8749087 = 8749550
571 + 8748979 = 8749550

Showing the first eight; more decompositions exist.
