Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722190, here are decompositions:

3 + 8722187 = 8722190
19 + 8722171 = 8722190
67 + 8722123 = 8722190
73 + 8722117 = 8722190
97 + 8722093 = 8722190
109 + 8722081 = 8722190
157 + 8722033 = 8722190
163 + 8722027 = 8722190

Showing the first eight; more decompositions exist.
