Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648242, here are decompositions:

3 + 8648239 = 8648242
131 + 8648111 = 8648242
149 + 8648093 = 8648242
263 + 8647979 = 8648242
293 + 8647949 = 8648242
353 + 8647889 = 8648242
419 + 8647823 = 8648242
503 + 8647739 = 8648242

Showing the first eight; more decompositions exist.
