Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722392, here are decompositions:

31 + 8722361 = 8722392
53 + 8722339 = 8722392
59 + 8722333 = 8722392
61 + 8722331 = 8722392
89 + 8722303 = 8722392
101 + 8722291 = 8722392
109 + 8722283 = 8722392
181 + 8722211 = 8722392

Showing the first eight; more decompositions exist.
