Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722758, here are decompositions:

19 + 8722739 = 8722758
47 + 8722711 = 8722758
97 + 8722661 = 8722758
127 + 8722631 = 8722758
137 + 8722621 = 8722758
151 + 8722607 = 8722758
241 + 8722517 = 8722758
281 + 8722477 = 8722758

Showing the first eight; more decompositions exist.
