Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690980, here are decompositions:

  • 17 + 8690963 = 8690980
  • 29 + 8690951 = 8690980
  • 59 + 8690921 = 8690980
  • 113 + 8690867 = 8690980
  • 167 + 8690813 = 8690980
  • 191 + 8690789 = 8690980
  • 197 + 8690783 = 8690980
  • 239 + 8690741 = 8690980

Showing the first eight; more decompositions exist.
