Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722600, here are decompositions:

59 + 8722541 = 8722600
83 + 8722517 = 8722600
101 + 8722499 = 8722600
191 + 8722409 = 8722600
233 + 8722367 = 8722600
239 + 8722361 = 8722600
269 + 8722331 = 8722600
317 + 8722283 = 8722600

Showing the first eight; more decompositions exist.
