Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625146, here are decompositions:

73 + 8625073 = 8625146
139 + 8625007 = 8625146
193 + 8624953 = 8625146
373 + 8624773 = 8625146
433 + 8624713 = 8625146
547 + 8624599 = 8625146
643 + 8624503 = 8625146
823 + 8624323 = 8625146

Showing the first eight; more decompositions exist.
