Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743238, here are decompositions:

139 + 8743099 = 8743238
151 + 8743087 = 8743238
211 + 8743027 = 8743238
241 + 8742997 = 8743238
307 + 8742931 = 8743238
421 + 8742817 = 8743238
499 + 8742739 = 8743238
601 + 8742637 = 8743238

Showing the first eight; more decompositions exist.
