Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743520, here are decompositions:

7 + 8743513 = 8743520
31 + 8743489 = 8743520
61 + 8743459 = 8743520
67 + 8743453 = 8743520
73 + 8743447 = 8743520
103 + 8743417 = 8743520
109 + 8743411 = 8743520
127 + 8743393 = 8743520

Showing the first eight; more decompositions exist.
