Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743312, here are decompositions:

3 + 8743309 = 8743312
173 + 8743139 = 8743312
191 + 8743121 = 8743312
233 + 8743079 = 8743312
269 + 8743043 = 8743312
293 + 8743019 = 8743312
311 + 8743001 = 8743312
491 + 8742821 = 8743312

Showing the first eight; more decompositions exist.
