Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724806, here are decompositions:

3 + 8724803 = 8724806
7 + 8724799 = 8724806
19 + 8724787 = 8724806
67 + 8724739 = 8724806
109 + 8724697 = 8724806
157 + 8724649 = 8724806
163 + 8724643 = 8724806
313 + 8724493 = 8724806

Showing the first eight; more decompositions exist.
