Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722658, here are decompositions:

37 + 8722621 = 8722658
181 + 8722477 = 8722658
199 + 8722459 = 8722658
211 + 8722447 = 8722658
229 + 8722429 = 8722658
367 + 8722291 = 8722658
421 + 8722237 = 8722658
487 + 8722171 = 8722658

Showing the first eight; more decompositions exist.
