Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722830, here are decompositions:

31 + 8722799 = 8722830
41 + 8722789 = 8722830
73 + 8722757 = 8722830
157 + 8722673 = 8722830
199 + 8722631 = 8722830
223 + 8722607 = 8722830
227 + 8722603 = 8722830
313 + 8722517 = 8722830

Showing the first eight; more decompositions exist.
