Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724942, here are decompositions:

13 + 8724929 = 8724942
59 + 8724883 = 8724942
71 + 8724871 = 8724942
139 + 8724803 = 8724942
223 + 8724719 = 8724942
229 + 8724713 = 8724942
293 + 8724649 = 8724942
311 + 8724631 = 8724942

Showing the first eight; more decompositions exist.
