Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625584, here are decompositions:

5 + 31625579 = 31625584
17 + 31625567 = 31625584
47 + 31625537 = 31625584
131 + 31625453 = 31625584
173 + 31625411 = 31625584
191 + 31625393 = 31625584
233 + 31625351 = 31625584
281 + 31625303 = 31625584

Showing the first eight; more decompositions exist.
