Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724904, here are decompositions:

101 + 8724803 = 8724904
191 + 8724713 = 8724904
263 + 8724641 = 8724904
443 + 8724461 = 8724904
467 + 8724437 = 8724904
557 + 8724347 = 8724904
593 + 8724311 = 8724904
641 + 8724263 = 8724904

Showing the first eight; more decompositions exist.
