Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722214, here are decompositions:

3 + 8722211 = 8722214
43 + 8722171 = 8722214
97 + 8722117 = 8722214
181 + 8722033 = 8722214
307 + 8721907 = 8722214
331 + 8721883 = 8722214
337 + 8721877 = 8722214
541 + 8721673 = 8722214

Showing the first eight; more decompositions exist.
