Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670448, here are decompositions:

41 + 8670407 = 8670448
167 + 8670281 = 8670448
191 + 8670257 = 8670448
251 + 8670197 = 8670448
257 + 8670191 = 8670448
359 + 8670089 = 8670448
419 + 8670029 = 8670448
467 + 8669981 = 8670448

Showing the first eight; more decompositions exist.
