Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719486, here are decompositions:

3 + 8719483 = 8719486
107 + 8719379 = 8719486
137 + 8719349 = 8719486
179 + 8719307 = 8719486
197 + 8719289 = 8719486
233 + 8719253 = 8719486
263 + 8719223 = 8719486
353 + 8719133 = 8719486

Showing the first eight; more decompositions exist.
