Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619864, here are decompositions:

  • 5 + 8619859 = 8619864
  • 7 + 8619857 = 8619864
  • 47 + 8619817 = 8619864
  • 53 + 8619811 = 8619864
  • 67 + 8619797 = 8619864
  • 73 + 8619791 = 8619864
  • 151 + 8619713 = 8619864
  • 181 + 8619683 = 8619864

Showing the first eight; more decompositions exist.
