Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525054, here are decompositions:

17 + 31525037 = 31525054
23 + 31525031 = 31525054
47 + 31525007 = 31525054
191 + 31524863 = 31525054
257 + 31524797 = 31525054
263 + 31524791 = 31525054
467 + 31524587 = 31525054
521 + 31524533 = 31525054

Showing the first eight; more decompositions exist.
