Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722078, here are decompositions:

59 + 8722019 = 8722078
89 + 8721989 = 8722078
137 + 8721941 = 8722078
149 + 8721929 = 8722078
227 + 8721851 = 8722078
461 + 8721617 = 8722078
479 + 8721599 = 8722078
719 + 8721359 = 8722078

Showing the first eight; more decompositions exist.
