Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670912, here are decompositions:

43 + 8670869 = 8670912
101 + 8670811 = 8670912
139 + 8670773 = 8670912
199 + 8670713 = 8670912
233 + 8670679 = 8670912
293 + 8670619 = 8670912
353 + 8670559 = 8670912
359 + 8670553 = 8670912

Showing the first eight; more decompositions exist.
