Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727278, here are decompositions:

31 + 8727247 = 8727278
67 + 8727211 = 8727278
211 + 8727067 = 8727278
229 + 8727049 = 8727278
541 + 8726737 = 8727278
601 + 8726677 = 8727278
607 + 8726671 = 8727278
631 + 8726647 = 8727278

Showing the first eight; more decompositions exist.
