Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675872, here are decompositions:

3 + 8675869 = 8675872
11 + 8675861 = 8675872
59 + 8675813 = 8675872
173 + 8675699 = 8675872
251 + 8675621 = 8675872
281 + 8675591 = 8675872
431 + 8675441 = 8675872
563 + 8675309 = 8675872

Showing the first eight; more decompositions exist.
