Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719122, here are decompositions:

23 + 8719099 = 8719122
73 + 8719049 = 8719122
101 + 8719021 = 8719122
149 + 8718973 = 8719122
173 + 8718949 = 8719122
241 + 8718881 = 8719122
263 + 8718859 = 8719122
271 + 8718851 = 8719122

Showing the first eight; more decompositions exist.
