Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649382, here are decompositions:

11 + 8649371 = 8649382
29 + 8649353 = 8649382
59 + 8649323 = 8649382
83 + 8649299 = 8649382
89 + 8649293 = 8649382
191 + 8649191 = 8649382
311 + 8649071 = 8649382
353 + 8649029 = 8649382

Showing the first eight; more decompositions exist.
