Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625450, here are decompositions:

19 + 31625431 = 31625450
67 + 31625383 = 31625450
271 + 31625179 = 31625450
499 + 31624951 = 31625450
523 + 31624927 = 31625450
601 + 31624849 = 31625450
613 + 31624837 = 31625450
643 + 31624807 = 31625450

Showing the first eight; more decompositions exist.
