Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722546, here are decompositions:

5 + 8722541 = 8722546
29 + 8722517 = 8722546
47 + 8722499 = 8722546
137 + 8722409 = 8722546
179 + 8722367 = 8722546
263 + 8722283 = 8722546
353 + 8722193 = 8722546
359 + 8722187 = 8722546

Showing the first eight; more decompositions exist.
