Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724700, here are decompositions:

3 + 8724697 = 8724700
59 + 8724641 = 8724700
233 + 8724467 = 8724700
239 + 8724461 = 8724700
263 + 8724437 = 8724700
353 + 8724347 = 8724700
389 + 8724311 = 8724700
431 + 8724269 = 8724700

Showing the first eight; more decompositions exist.
