Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576070, here are decompositions:

  • 3 + 31576067 = 31576070
  • 61 + 31576009 = 31576070
  • 67 + 31576003 = 31576070
  • 79 + 31575991 = 31576070
  • 193 + 31575877 = 31576070
  • 241 + 31575829 = 31576070
  • 271 + 31575799 = 31576070
  • 277 + 31575793 = 31576070

Showing the first eight; more decompositions exist.
