Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527042, here are decompositions:

  • 31 + 31527011 = 31527042
  • 89 + 31526953 = 31527042
  • 101 + 31526941 = 31527042
  • 103 + 31526939 = 31527042
  • 139 + 31526903 = 31527042
  • 149 + 31526893 = 31527042
  • 163 + 31526879 = 31527042
  • 179 + 31526863 = 31527042

Showing the first eight; more decompositions exist.
