Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751390, here are decompositions:

19 + 8751371 = 8751390
23 + 8751367 = 8751390
41 + 8751349 = 8751390
61 + 8751329 = 8751390
71 + 8751319 = 8751390
101 + 8751289 = 8751390
139 + 8751251 = 8751390
157 + 8751233 = 8751390

Showing the first eight; more decompositions exist.
