Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625354, here are decompositions:

3 + 31625351 = 31625354
73 + 31625281 = 31625354
223 + 31625131 = 31625354
433 + 31624921 = 31625354
547 + 31624807 = 31625354
571 + 31624783 = 31625354
601 + 31624753 = 31625354
613 + 31624741 = 31625354

Showing the first eight; more decompositions exist.
