Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625456, here are decompositions:

3 + 31625453 = 31625456
73 + 31625383 = 31625456
193 + 31625263 = 31625456
277 + 31625179 = 31625456
307 + 31625149 = 31625456
397 + 31625059 = 31625456
607 + 31624849 = 31625456
619 + 31624837 = 31625456

Showing the first eight; more decompositions exist.
