Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719840, here are decompositions:

23 + 8719817 = 8719840
137 + 8719703 = 8719840
179 + 8719661 = 8719840
263 + 8719577 = 8719840
419 + 8719421 = 8719840
449 + 8719391 = 8719840
461 + 8719379 = 8719840
491 + 8719349 = 8719840

Showing the first eight; more decompositions exist.
