Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742070, here are decompositions:

  • 3 + 8742067 = 8742070
  • 11 + 8742059 = 8742070
  • 59 + 8742011 = 8742070
  • 83 + 8741987 = 8742070
  • 137 + 8741933 = 8742070
  • 257 + 8741813 = 8742070
  • 269 + 8741801 = 8742070
  • 317 + 8741753 = 8742070

Showing the first eight; more decompositions exist.
