Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592120, here are decompositions:

  • 67 + 31592053 = 31592120
  • 73 + 31592047 = 31592120
  • 127 + 31591993 = 31592120
  • 163 + 31591957 = 31592120
  • 211 + 31591909 = 31592120
  • 277 + 31591843 = 31592120
  • 283 + 31591837 = 31592120
  • 337 + 31591783 = 31592120

Showing the first eight; more decompositions exist.
