Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724664, here are decompositions:

23 + 8724641 = 8724664
167 + 8724497 = 8724664
197 + 8724467 = 8724664
227 + 8724437 = 8724664
293 + 8724371 = 8724664
317 + 8724347 = 8724664
353 + 8724311 = 8724664
401 + 8724263 = 8724664

Showing the first eight; more decompositions exist.
