Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719690, here are decompositions:

29 + 8719661 = 8719690
113 + 8719577 = 8719690
149 + 8719541 = 8719690
269 + 8719421 = 8719690
311 + 8719379 = 8719690
383 + 8719307 = 8719690
389 + 8719301 = 8719690
401 + 8719289 = 8719690

Showing the first eight; more decompositions exist.
