Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742534, here are decompositions:

5 + 8742529 = 8742534
23 + 8742511 = 8742534
37 + 8742497 = 8742534
41 + 8742493 = 8742534
71 + 8742463 = 8742534
113 + 8742421 = 8742534
167 + 8742367 = 8742534
181 + 8742353 = 8742534

Showing the first eight; more decompositions exist.
