Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525102, here are decompositions:

71 + 31525031 = 31525102
113 + 31524989 = 31525102
239 + 31524863 = 31525102
263 + 31524839 = 31525102
293 + 31524809 = 31525102
311 + 31524791 = 31525102
461 + 31524641 = 31525102
569 + 31524533 = 31525102

Showing the first eight; more decompositions exist.
