Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625394, here are decompositions:

83 + 8625311 = 8625394
131 + 8625263 = 8625394
191 + 8625203 = 8625394
263 + 8625131 = 8625394
311 + 8625083 = 8625394
317 + 8625077 = 8625394
383 + 8625011 = 8625394
521 + 8624873 = 8625394

Showing the first eight; more decompositions exist.
