Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748266, here are decompositions:

3 + 8748263 = 8748266
67 + 8748199 = 8748266
157 + 8748109 = 8748266
223 + 8748043 = 8748266
337 + 8747929 = 8748266
349 + 8747917 = 8748266
409 + 8747857 = 8748266
463 + 8747803 = 8748266

Showing the first eight; more decompositions exist.
