Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743458, here are decompositions:

5 + 8743453 = 8743458
11 + 8743447 = 8743458
37 + 8743421 = 8743458
41 + 8743417 = 8743458
47 + 8743411 = 8743458
79 + 8743379 = 8743458
109 + 8743349 = 8743458
127 + 8743331 = 8743458

Showing the first eight; more decompositions exist.
