Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743578, here are decompositions:

7 + 8743571 = 8743578
17 + 8743561 = 8743578
29 + 8743549 = 8743578
31 + 8743547 = 8743578
47 + 8743531 = 8743578
79 + 8743499 = 8743578
89 + 8743489 = 8743578
131 + 8743447 = 8743578

Showing the first eight; more decompositions exist.
