Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751382, here are decompositions:

11 + 8751371 = 8751382
41 + 8751341 = 8751382
53 + 8751329 = 8751382
131 + 8751251 = 8751382
149 + 8751233 = 8751382
239 + 8751143 = 8751382
281 + 8751101 = 8751382
293 + 8751089 = 8751382

Showing the first eight; more decompositions exist.
