Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724738, here are decompositions:

17 + 8724721 = 8724738
19 + 8724719 = 8724738
41 + 8724697 = 8724738
89 + 8724649 = 8724738
97 + 8724641 = 8724738
107 + 8724631 = 8724738
137 + 8724601 = 8724738
149 + 8724589 = 8724738

Showing the first eight; more decompositions exist.
