Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743530, here are decompositions:

17 + 8743513 = 8743530
31 + 8743499 = 8743530
41 + 8743489 = 8743530
71 + 8743459 = 8743530
83 + 8743447 = 8743530
109 + 8743421 = 8743530
113 + 8743417 = 8743530
137 + 8743393 = 8743530

Showing the first eight; more decompositions exist.
