Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684072, here are decompositions:

3 + 8684069 = 8684072
43 + 8684029 = 8684072
139 + 8683933 = 8684072
349 + 8683723 = 8684072
373 + 8683699 = 8684072
379 + 8683693 = 8684072
409 + 8683663 = 8684072
433 + 8683639 = 8684072

Showing the first eight; more decompositions exist.
