Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722774, here are decompositions:

17 + 8722757 = 8722774
101 + 8722673 = 8722774
113 + 8722661 = 8722774
131 + 8722643 = 8722774
167 + 8722607 = 8722774
233 + 8722541 = 8722774
257 + 8722517 = 8722774
383 + 8722391 = 8722774

Showing the first eight; more decompositions exist.
