Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1936, here are decompositions:

  • 3 + 1933 = 1936
  • 5 + 1931 = 1936
  • 23 + 1913 = 1936
  • 29 + 1907 = 1936
  • 47 + 1889 = 1936
  • 59 + 1877 = 1936
  • 89 + 1847 = 1936
  • 113 + 1823 = 1936

Showing the first eight; more decompositions exist.
