Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743518, here are decompositions:

5 + 8743513 = 8743518
19 + 8743499 = 8743518
29 + 8743489 = 8743518
59 + 8743459 = 8743518
71 + 8743447 = 8743518
97 + 8743421 = 8743518
101 + 8743417 = 8743518
107 + 8743411 = 8743518

Showing the first eight; more decompositions exist.
