Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651244, here are decompositions:

5 + 8651239 = 8651244
11 + 8651233 = 8651244
13 + 8651231 = 8651244
37 + 8651207 = 8651244
53 + 8651191 = 8651244
83 + 8651161 = 8651244
101 + 8651143 = 8651244
103 + 8651141 = 8651244

Showing the first eight; more decompositions exist.
