Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727072, here are decompositions:

5 + 8727067 = 8727072
19 + 8727053 = 8727072
23 + 8727049 = 8727072
41 + 8727031 = 8727072
83 + 8726989 = 8727072
89 + 8726983 = 8727072
103 + 8726969 = 8727072
149 + 8726923 = 8727072

Showing the first eight; more decompositions exist.
