Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71900, here are decompositions:

  • 13 + 71887 = 71900
  • 19 + 71881 = 71900
  • 79 + 71821 = 71900
  • 139 + 71761 = 71900
  • 181 + 71719 = 71900
  • 193 + 71707 = 71900
  • 229 + 71671 = 71900
  • 307 + 71593 = 71900

Showing the first eight; more decompositions exist.
