Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672240, here are decompositions:

37 + 8672203 = 8672240
79 + 8672161 = 8672240
139 + 8672101 = 8672240
193 + 8672047 = 8672240
571 + 8671669 = 8672240
601 + 8671639 = 8672240
607 + 8671633 = 8672240
691 + 8671549 = 8672240

Showing the first eight; more decompositions exist.
