Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751442, here are decompositions:

3 + 8751439 = 8751442
41 + 8751401 = 8751442
71 + 8751371 = 8751442
101 + 8751341 = 8751442
113 + 8751329 = 8751442
191 + 8751251 = 8751442
269 + 8751173 = 8751442
353 + 8751089 = 8751442

Showing the first eight; more decompositions exist.
