Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625444, here are decompositions:

13 + 31625431 = 31625444
43 + 31625401 = 31625444
61 + 31625383 = 31625444
163 + 31625281 = 31625444
181 + 31625263 = 31625444
313 + 31625131 = 31625444
523 + 31624921 = 31625444
607 + 31624837 = 31625444

Showing the first eight; more decompositions exist.
