Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722562, here are decompositions:

103 + 8722459 = 8722562
139 + 8722423 = 8722562
223 + 8722339 = 8722562
229 + 8722333 = 8722562
271 + 8722291 = 8722562
439 + 8722123 = 8722562
463 + 8722099 = 8722562
1021 + 8721541 = 8722562

Showing the first eight; more decompositions exist.
