Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634878, here are decompositions:

  • 19 + 8634859 = 8634878
  • 37 + 8634841 = 8634878
  • 67 + 8634811 = 8634878
  • 127 + 8634751 = 8634878
  • 181 + 8634697 = 8634878
  • 199 + 8634679 = 8634878
  • 211 + 8634667 = 8634878
  • 397 + 8634481 = 8634878

Showing the first eight; more decompositions exist.
