Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670378, here are decompositions:

5 + 8670373 = 8670378
7 + 8670371 = 8670378
47 + 8670331 = 8670378
97 + 8670281 = 8670378
139 + 8670239 = 8670378
181 + 8670197 = 8670378
251 + 8670127 = 8670378
271 + 8670107 = 8670378

Showing the first eight; more decompositions exist.
