Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736448, here are decompositions:

47 + 8736401 = 8736448
107 + 8736341 = 8736448
239 + 8736209 = 8736448
257 + 8736191 = 8736448
269 + 8736179 = 8736448
359 + 8736089 = 8736448
389 + 8736059 = 8736448
557 + 8735891 = 8736448

Showing the first eight; more decompositions exist.
