Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610060, here are decompositions:

  • 37 + 31610023 = 31610060
  • 67 + 31609993 = 31610060
  • 103 + 31609957 = 31610060
  • 127 + 31609933 = 31610060
  • 199 + 31609861 = 31610060
  • 211 + 31609849 = 31610060
  • 241 + 31609819 = 31610060
  • 283 + 31609777 = 31610060

Showing the first eight; more decompositions exist.
