Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724658, here are decompositions:

17 + 8724641 = 8724658
179 + 8724479 = 8724658
191 + 8724467 = 8724658
197 + 8724461 = 8724658
281 + 8724377 = 8724658
311 + 8724347 = 8724658
347 + 8724311 = 8724658
389 + 8724269 = 8724658

Showing the first eight; more decompositions exist.
