Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750392, here are decompositions:

5 + 8750387 = 8750392
23 + 8750369 = 8750392
29 + 8750363 = 8750392
41 + 8750351 = 8750392
59 + 8750333 = 8750392
71 + 8750321 = 8750392
83 + 8750309 = 8750392
149 + 8750243 = 8750392

Showing the first eight; more decompositions exist.
