Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745448, here are decompositions:

11 + 8745437 = 8745448
29 + 8745419 = 8745448
137 + 8745311 = 8745448
149 + 8745299 = 8745448
347 + 8745101 = 8745448
431 + 8745017 = 8745448
479 + 8744969 = 8745448
521 + 8744927 = 8745448

Showing the first eight; more decompositions exist.
