Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751424, here are decompositions:

23 + 8751401 = 8751424
53 + 8751371 = 8751424
83 + 8751341 = 8751424
167 + 8751257 = 8751424
173 + 8751251 = 8751424
191 + 8751233 = 8751424
251 + 8751173 = 8751424
281 + 8751143 = 8751424

Showing the first eight; more decompositions exist.
