Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625378, here are decompositions:

19 + 8625359 = 8625378
29 + 8625349 = 8625378
61 + 8625317 = 8625378
67 + 8625311 = 8625378
89 + 8625289 = 8625378
131 + 8625247 = 8625378
149 + 8625229 = 8625378
191 + 8625187 = 8625378

Showing the first eight; more decompositions exist.
