Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590292, here are decompositions:

  • 23 + 31590269 = 31590292
  • 29 + 31590263 = 31590292
  • 131 + 31590161 = 31590292
  • 281 + 31590011 = 31590292
  • 311 + 31589981 = 31590292
  • 401 + 31589891 = 31590292
  • 431 + 31589861 = 31590292
  • 449 + 31589843 = 31590292

Showing the first eight; more decompositions exist.
