Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722538, here are decompositions:

61 + 8722477 = 8722538
67 + 8722471 = 8722538
79 + 8722459 = 8722538
109 + 8722429 = 8722538
199 + 8722339 = 8722538
241 + 8722297 = 8722538
367 + 8722171 = 8722538
421 + 8722117 = 8722538

Showing the first eight; more decompositions exist.
