Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89980, here are decompositions:

  • 3 + 89977 = 89980
  • 17 + 89963 = 89980
  • 41 + 89939 = 89980
  • 71 + 89909 = 89980
  • 83 + 89897 = 89980
  • 89 + 89891 = 89980
  • 113 + 89867 = 89980
  • 131 + 89849 = 89980

Showing the first eight; more decompositions exist.
