Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722498, here are decompositions:

89 + 8722409 = 8722498
107 + 8722391 = 8722498
131 + 8722367 = 8722498
137 + 8722361 = 8722498
167 + 8722331 = 8722498
311 + 8722187 = 8722498
401 + 8722097 = 8722498
419 + 8722079 = 8722498

Showing the first eight; more decompositions exist.
