Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71390, here are decompositions:

  • 3 + 71387 = 71390
  • 31 + 71359 = 71390
  • 37 + 71353 = 71390
  • 43 + 71347 = 71390
  • 61 + 71329 = 71390
  • 73 + 71317 = 71390
  • 97 + 71293 = 71390
  • 103 + 71287 = 71390

Showing the first eight; more decompositions exist.
