Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743542, here are decompositions:

11 + 8743531 = 8743542
29 + 8743513 = 8743542
43 + 8743499 = 8743542
53 + 8743489 = 8743542
83 + 8743459 = 8743542
89 + 8743453 = 8743542
131 + 8743411 = 8743542
149 + 8743393 = 8743542

Showing the first eight; more decompositions exist.
