Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722424, here are decompositions:

31 + 8722393 = 8722424
127 + 8722297 = 8722424
307 + 8722117 = 8722424
331 + 8722093 = 8722424
397 + 8722027 = 8722424
541 + 8721883 = 8722424
547 + 8721877 = 8722424
661 + 8721763 = 8722424

Showing the first eight; more decompositions exist.
