Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722046, here are decompositions:

13 + 8722033 = 8722046
19 + 8722027 = 8722046
37 + 8722009 = 8722046
139 + 8721907 = 8722046
163 + 8721883 = 8722046
283 + 8721763 = 8722046
373 + 8721673 = 8722046
379 + 8721667 = 8722046

Showing the first eight; more decompositions exist.
