Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712378, here are decompositions:

5 + 8712373 = 8712378
7 + 8712371 = 8712378
11 + 8712367 = 8712378
29 + 8712349 = 8712378
41 + 8712337 = 8712378
67 + 8712311 = 8712378
71 + 8712307 = 8712378
97 + 8712281 = 8712378

Showing the first eight; more decompositions exist.
