Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670872, here are decompositions:

3 + 8670869 = 8670872
61 + 8670811 = 8670872
163 + 8670709 = 8670872
193 + 8670679 = 8670872
283 + 8670589 = 8670872
313 + 8670559 = 8670872
349 + 8670523 = 8670872
373 + 8670499 = 8670872

Showing the first eight; more decompositions exist.
