Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649242, here are decompositions:

3 + 8649239 = 8649242
31 + 8649211 = 8649242
139 + 8649103 = 8649242
163 + 8649079 = 8649242
181 + 8649061 = 8649242
193 + 8649049 = 8649242
241 + 8649001 = 8649242
313 + 8648929 = 8649242

Showing the first eight; more decompositions exist.
