Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749448, here are decompositions:

31 + 8749417 = 8749448
139 + 8749309 = 8749448
229 + 8749219 = 8749448
241 + 8749207 = 8749448
307 + 8749141 = 8749448
457 + 8748991 = 8749448
571 + 8748877 = 8749448
601 + 8748847 = 8749448

Showing the first eight; more decompositions exist.
