Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672078, here are decompositions:

31 + 8672047 = 8672078
97 + 8671981 = 8672078
241 + 8671837 = 8672078
367 + 8671711 = 8672078
409 + 8671669 = 8672078
439 + 8671639 = 8672078
577 + 8671501 = 8672078
607 + 8671471 = 8672078

Showing the first eight; more decompositions exist.
