Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625752, here are decompositions:

29 + 31625723 = 31625752
71 + 31625681 = 31625752
101 + 31625651 = 31625752
149 + 31625603 = 31625752
173 + 31625579 = 31625752
359 + 31625393 = 31625752
401 + 31625351 = 31625752
449 + 31625303 = 31625752

Showing the first eight; more decompositions exist.
