Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704890, here are decompositions:

  • 37 + 8704853 = 8704890
  • 53 + 8704837 = 8704890
  • 79 + 8704811 = 8704890
  • 107 + 8704783 = 8704890
  • 113 + 8704777 = 8704890
  • 167 + 8704723 = 8704890
  • 179 + 8704711 = 8704890
  • 191 + 8704699 = 8704890

Showing the first eight; more decompositions exist.
