Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625458, here are decompositions:

5 + 31625453 = 31625458
47 + 31625411 = 31625458
107 + 31625351 = 31625458
197 + 31625261 = 31625458
311 + 31625147 = 31625458
401 + 31625057 = 31625458
419 + 31625039 = 31625458
479 + 31624979 = 31625458

Showing the first eight; more decompositions exist.
