Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742586, here are decompositions:

89 + 8742497 = 8742586
137 + 8742449 = 8742586
227 + 8742359 = 8742586
233 + 8742353 = 8742586
239 + 8742347 = 8742586
269 + 8742317 = 8742586
389 + 8742197 = 8742586
509 + 8742077 = 8742586

Showing the first eight; more decompositions exist.
