Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661272, here are decompositions:

19 + 8661253 = 8661272
31 + 8661241 = 8661272
79 + 8661193 = 8661272
211 + 8661061 = 8661272
223 + 8661049 = 8661272
229 + 8661043 = 8661272
271 + 8661001 = 8661272
409 + 8660863 = 8661272

Showing the first eight; more decompositions exist.
