Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536220, here are decompositions:

  • 17 + 31536203 = 31536220
  • 59 + 31536161 = 31536220
  • 167 + 31536053 = 31536220
  • 239 + 31535981 = 31536220
  • 281 + 31535939 = 31536220
  • 311 + 31535909 = 31536220
  • 389 + 31535831 = 31536220
  • 467 + 31535753 = 31536220

Showing the first eight; more decompositions exist.
