Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608754, here are decompositions:

5 + 31608749 = 31608754
17 + 31608737 = 31608754
41 + 31608713 = 31608754
167 + 31608587 = 31608754
227 + 31608527 = 31608754
257 + 31608497 = 31608754
491 + 31608263 = 31608754
587 + 31608167 = 31608754

Showing the first eight; more decompositions exist.
