Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706448, here are decompositions:

29 + 8706419 = 8706448
41 + 8706407 = 8706448
71 + 8706377 = 8706448
197 + 8706251 = 8706448
227 + 8706221 = 8706448
251 + 8706197 = 8706448
347 + 8706101 = 8706448
389 + 8706059 = 8706448

Showing the first eight; more decompositions exist.
