Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634870, here are decompositions:

  • 7 + 8634863 = 8634870
  • 11 + 8634859 = 8634870
  • 19 + 8634851 = 8634870
  • 29 + 8634841 = 8634870
  • 31 + 8634839 = 8634870
  • 47 + 8634823 = 8634870
  • 59 + 8634811 = 8634870
  • 67 + 8634803 = 8634870

Showing the first eight; more decompositions exist.
