Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590760, here are decompositions:

  • 23 + 31590737 = 31590760
  • 29 + 31590731 = 31590760
  • 101 + 31590659 = 31590760
  • 167 + 31590593 = 31590760
  • 281 + 31590479 = 31590760
  • 293 + 31590467 = 31590760
  • 317 + 31590443 = 31590760
  • 347 + 31590413 = 31590760

Showing the first eight; more decompositions exist.
