Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529164, here are decompositions:

83 + 31529081 = 31529164
167 + 31528997 = 31529164
197 + 31528967 = 31529164
311 + 31528853 = 31529164
353 + 31528811 = 31529164
467 + 31528697 = 31529164
617 + 31528547 = 31529164
827 + 31528337 = 31529164

Showing the first eight; more decompositions exist.
