Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670928, here are decompositions:

41 + 8670887 = 8670928
59 + 8670869 = 8670928
137 + 8670791 = 8670928
317 + 8670611 = 8670928
419 + 8670509 = 8670928
521 + 8670407 = 8670928
557 + 8670371 = 8670928
647 + 8670281 = 8670928

Showing the first eight; more decompositions exist.
