Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672072, here are decompositions:

433 + 8671639 = 8672072
439 + 8671633 = 8672072
499 + 8671573 = 8672072
523 + 8671549 = 8672072
571 + 8671501 = 8672072
601 + 8671471 = 8672072
631 + 8671441 = 8672072
691 + 8671381 = 8672072

Showing the first eight; more decompositions exist.
