Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724906, here are decompositions:

23 + 8724883 = 8724906
59 + 8724847 = 8724906
79 + 8724827 = 8724906
103 + 8724803 = 8724906
107 + 8724799 = 8724906
167 + 8724739 = 8724906
193 + 8724713 = 8724906
257 + 8724649 = 8724906

Showing the first eight; more decompositions exist.
