Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1950, here are decompositions:

  • 17 + 1933 = 1950
  • 19 + 1931 = 1950
  • 37 + 1913 = 1950
  • 43 + 1907 = 1950
  • 61 + 1889 = 1950
  • 71 + 1879 = 1950
  • 73 + 1877 = 1950
  • 79 + 1871 = 1950

Showing the first eight; more decompositions exist.
