Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639048, here are decompositions:

37 + 8639011 = 8639048
97 + 8638951 = 8639048
139 + 8638909 = 8639048
157 + 8638891 = 8639048
181 + 8638867 = 8639048
199 + 8638849 = 8639048
241 + 8638807 = 8639048
421 + 8638627 = 8639048

Showing the first eight; more decompositions exist.
