Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724938, here are decompositions:

67 + 8724871 = 8724938
139 + 8724799 = 8724938
151 + 8724787 = 8724938
199 + 8724739 = 8724938
241 + 8724697 = 8724938
307 + 8724631 = 8724938
337 + 8724601 = 8724938
349 + 8724589 = 8724938

Showing the first eight; more decompositions exist.
