Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731080, here are decompositions:

11 + 8731069 = 8731080
41 + 8731039 = 8731080
53 + 8731027 = 8731080
97 + 8730983 = 8731080
103 + 8730977 = 8731080
131 + 8730949 = 8731080
151 + 8730929 = 8731080
167 + 8730913 = 8731080

Showing the first eight; more decompositions exist.
