Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634890, here are decompositions:

  • 7 + 8634883 = 8634890
  • 31 + 8634859 = 8634890
  • 67 + 8634823 = 8634890
  • 79 + 8634811 = 8634890
  • 139 + 8634751 = 8634890
  • 193 + 8634697 = 8634890
  • 211 + 8634679 = 8634890
  • 223 + 8634667 = 8634890

Showing the first eight; more decompositions exist.
