Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722792, here are decompositions:

3 + 8722789 = 8722792
53 + 8722739 = 8722792
131 + 8722661 = 8722792
149 + 8722643 = 8722792
179 + 8722613 = 8722792
251 + 8722541 = 8722792
293 + 8722499 = 8722792
383 + 8722409 = 8722792

Showing the first eight; more decompositions exist.
