Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724966, here are decompositions:

17 + 8724949 = 8724966
23 + 8724943 = 8724966
37 + 8724929 = 8724966
83 + 8724883 = 8724966
139 + 8724827 = 8724966
163 + 8724803 = 8724966
167 + 8724799 = 8724966
179 + 8724787 = 8724966

Showing the first eight; more decompositions exist.
