Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525556, here are decompositions:

3 + 31525553 = 31525556
19 + 31525537 = 31525556
67 + 31525489 = 31525556
79 + 31525477 = 31525556
109 + 31525447 = 31525556
277 + 31525279 = 31525556
313 + 31525243 = 31525556
373 + 31525183 = 31525556

Showing the first eight; more decompositions exist.
