Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724198, here are decompositions:

17 + 8724181 = 8724198
29 + 8724169 = 8724198
37 + 8724161 = 8724198
59 + 8724139 = 8724198
71 + 8724127 = 8724198
97 + 8724101 = 8724198
127 + 8724071 = 8724198
211 + 8723987 = 8724198

Showing the first eight; more decompositions exist.
