Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719390, here are decompositions:

11 + 8719379 = 8719390
23 + 8719367 = 8719390
41 + 8719349 = 8719390
83 + 8719307 = 8719390
89 + 8719301 = 8719390
101 + 8719289 = 8719390
137 + 8719253 = 8719390
167 + 8719223 = 8719390

Showing the first eight; more decompositions exist.
