Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746840, here are decompositions:

29 + 8746811 = 8746840
41 + 8746799 = 8746840
83 + 8746757 = 8746840
107 + 8746733 = 8746840
131 + 8746709 = 8746840
449 + 8746391 = 8746840
461 + 8746379 = 8746840
569 + 8746271 = 8746840

Showing the first eight; more decompositions exist.
