Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751372, here are decompositions:

5 + 8751367 = 8751372
23 + 8751349 = 8751372
31 + 8751341 = 8751372
43 + 8751329 = 8751372
53 + 8751319 = 8751372
83 + 8751289 = 8751372
139 + 8751233 = 8751372
151 + 8751221 = 8751372

Showing the first eight; more decompositions exist.
