Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722462, here are decompositions:

3 + 8722459 = 8722462
53 + 8722409 = 8722462
71 + 8722391 = 8722462
101 + 8722361 = 8722462
131 + 8722331 = 8722462
179 + 8722283 = 8722462
239 + 8722223 = 8722462
251 + 8722211 = 8722462

Showing the first eight; more decompositions exist.
