Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722586, here are decompositions:

109 + 8722477 = 8722586
127 + 8722459 = 8722586
139 + 8722447 = 8722586
157 + 8722429 = 8722586
163 + 8722423 = 8722586
193 + 8722393 = 8722586
283 + 8722303 = 8722586
349 + 8722237 = 8722586

Showing the first eight; more decompositions exist.
