Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525024, here are decompositions:

17 + 31525007 = 31525024
131 + 31524893 = 31525024
227 + 31524797 = 31525024
233 + 31524791 = 31525024
257 + 31524767 = 31525024
347 + 31524677 = 31525024
383 + 31524641 = 31525024
491 + 31524533 = 31525024

Showing the first eight; more decompositions exist.
