Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721498, here are decompositions:

11 + 8721487 = 8721498
17 + 8721481 = 8721498
29 + 8721469 = 8721498
31 + 8721467 = 8721498
127 + 8721371 = 8721498
139 + 8721359 = 8721498
199 + 8721299 = 8721498
229 + 8721269 = 8721498

Showing the first eight; more decompositions exist.
