Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672842, here are decompositions:

11 + 8672831 = 8672842
23 + 8672819 = 8672842
41 + 8672801 = 8672842
53 + 8672789 = 8672842
281 + 8672561 = 8672842
359 + 8672483 = 8672842
401 + 8672441 = 8672842
419 + 8672423 = 8672842

Showing the first eight; more decompositions exist.
