Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527070, here are decompositions:

  • 23 + 31527047 = 31527070
  • 53 + 31527017 = 31527070
  • 59 + 31527011 = 31527070
  • 131 + 31526939 = 31527070
  • 149 + 31526921 = 31527070
  • 167 + 31526903 = 31527070
  • 191 + 31526879 = 31527070
  • 251 + 31526819 = 31527070

Showing the first eight; more decompositions exist.
