Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669072, here are decompositions:

31 + 8669041 = 8669072
79 + 8668993 = 8669072
199 + 8668873 = 8669072
241 + 8668831 = 8669072
271 + 8668801 = 8669072
331 + 8668741 = 8669072
463 + 8668609 = 8669072
523 + 8668549 = 8669072

Showing the first eight; more decompositions exist.
