Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700378, here are decompositions:

17 + 8700361 = 8700378
79 + 8700299 = 8700378
97 + 8700281 = 8700378
139 + 8700239 = 8700378
257 + 8700121 = 8700378
307 + 8700071 = 8700378
331 + 8700047 = 8700378
347 + 8700031 = 8700378

Showing the first eight; more decompositions exist.
