Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722468, here are decompositions:

59 + 8722409 = 8722468
101 + 8722367 = 8722468
107 + 8722361 = 8722468
137 + 8722331 = 8722468
257 + 8722211 = 8722468
281 + 8722187 = 8722468
389 + 8722079 = 8722468
449 + 8722019 = 8722468

Showing the first eight; more decompositions exist.
