Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634920, here are decompositions:

  • 3 + 8634917 = 8634920
  • 13 + 8634907 = 8634920
  • 31 + 8634889 = 8634920
  • 37 + 8634883 = 8634920
  • 61 + 8634859 = 8634920
  • 79 + 8634841 = 8634920
  • 97 + 8634823 = 8634920
  • 109 + 8634811 = 8634920

Showing the first eight; more decompositions exist.
