Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625358, here are decompositions:

7 + 31625351 = 31625358
97 + 31625261 = 31625358
179 + 31625179 = 31625358
211 + 31625147 = 31625358
227 + 31625131 = 31625358
379 + 31624979 = 31625358
419 + 31624939 = 31625358
431 + 31624927 = 31625358

Showing the first eight; more decompositions exist.
