Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670442, here are decompositions:

71 + 8670371 = 8670442
89 + 8670353 = 8670442
251 + 8670191 = 8670442
353 + 8670089 = 8670442
401 + 8670041 = 8670442
449 + 8669993 = 8670442
461 + 8669981 = 8670442
479 + 8669963 = 8670442

Showing the first eight; more decompositions exist.
