Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722838, here are decompositions:

127 + 8722711 = 8722838
367 + 8722471 = 8722838
379 + 8722459 = 8722838
409 + 8722429 = 8722838
499 + 8722339 = 8722838
541 + 8722297 = 8722838
547 + 8722291 = 8722838
601 + 8722237 = 8722838

Showing the first eight; more decompositions exist.
