Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84870, here are decompositions:

  • 11 + 84859 = 84870
  • 13 + 84857 = 84870
  • 43 + 84827 = 84870
  • 59 + 84811 = 84870
  • 61 + 84809 = 84870
  • 83 + 84787 = 84870
  • 109 + 84761 = 84870
  • 139 + 84731 = 84870

Showing the first eight; more decompositions exist.
