Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727132, here are decompositions:

13 + 8727119 = 8727132
19 + 8727113 = 8727132
23 + 8727109 = 8727132
41 + 8727091 = 8727132
79 + 8727053 = 8727132
83 + 8727049 = 8727132
101 + 8727031 = 8727132
149 + 8726983 = 8727132

Showing the first eight; more decompositions exist.
