Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625478, here are decompositions:

11 + 8625467 = 8625478
47 + 8625431 = 8625478
167 + 8625311 = 8625478
347 + 8625131 = 8625478
359 + 8625119 = 8625478
401 + 8625077 = 8625478
419 + 8625059 = 8625478
467 + 8625011 = 8625478

Showing the first eight; more decompositions exist.
