Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742748, here are decompositions:

59 + 8742689 = 8742748
71 + 8742677 = 8742748
197 + 8742551 = 8742748
251 + 8742497 = 8742748
347 + 8742401 = 8742748
389 + 8742359 = 8742748
401 + 8742347 = 8742748
431 + 8742317 = 8742748

Showing the first eight; more decompositions exist.
