Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671072, here are decompositions:

5 + 8671067 = 8671072
41 + 8671031 = 8671072
83 + 8670989 = 8671072
131 + 8670941 = 8671072
281 + 8670791 = 8671072
359 + 8670713 = 8671072
419 + 8670653 = 8671072
461 + 8670611 = 8671072

Showing the first eight; more decompositions exist.
