Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689130, here are decompositions:

  • 19 + 8689111 = 8689130
  • 61 + 8689069 = 8689130
  • 67 + 8689063 = 8689130
  • 97 + 8689033 = 8689130
  • 139 + 8688991 = 8689130
  • 211 + 8688919 = 8689130
  • 313 + 8688817 = 8689130
  • 433 + 8688697 = 8689130

Showing the first eight; more decompositions exist.
