Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527100, here are decompositions:

  • 23 + 31527077 = 31527100
  • 53 + 31527047 = 31527100
  • 83 + 31527017 = 31527100
  • 89 + 31527011 = 31527100
  • 173 + 31526927 = 31527100
  • 179 + 31526921 = 31527100
  • 197 + 31526903 = 31527100
  • 281 + 31526819 = 31527100

Showing the first eight; more decompositions exist.
