Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662238, here are decompositions:

19 + 8662219 = 8662238
37 + 8662201 = 8662238
61 + 8662177 = 8662238
181 + 8662057 = 8662238
229 + 8662009 = 8662238
241 + 8661997 = 8662238
337 + 8661901 = 8662238
349 + 8661889 = 8662238

Showing the first eight; more decompositions exist.
