Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751844, here are decompositions:

5 + 8751839 = 8751844
41 + 8751803 = 8751844
71 + 8751773 = 8751844
173 + 8751671 = 8751844
251 + 8751593 = 8751844
281 + 8751563 = 8751844
317 + 8751527 = 8751844
383 + 8751461 = 8751844

Showing the first eight; more decompositions exist.
