Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669782, here are decompositions:

5 + 8669777 = 8669782
113 + 8669669 = 8669782
131 + 8669651 = 8669782
239 + 8669543 = 8669782
269 + 8669513 = 8669782
281 + 8669501 = 8669782
293 + 8669489 = 8669782
383 + 8669399 = 8669782

Showing the first eight; more decompositions exist.
