Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743540, here are decompositions:

41 + 8743499 = 8743540
131 + 8743409 = 8743540
173 + 8743367 = 8743540
191 + 8743349 = 8743540
263 + 8743277 = 8743540
401 + 8743139 = 8743540
419 + 8743121 = 8743540
461 + 8743079 = 8743540

Showing the first eight; more decompositions exist.
