Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722492, here are decompositions:

83 + 8722409 = 8722492
101 + 8722391 = 8722492
131 + 8722361 = 8722492
269 + 8722223 = 8722492
281 + 8722211 = 8722492
491 + 8722001 = 8722492
503 + 8721989 = 8722492
563 + 8721929 = 8722492

Showing the first eight; more decompositions exist.
