Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1914, here are decompositions:

  • 7 + 1907 = 1914
  • 13 + 1901 = 1914
  • 37 + 1877 = 1914
  • 41 + 1873 = 1914
  • 43 + 1871 = 1914
  • 47 + 1867 = 1914
  • 53 + 1861 = 1914
  • 67 + 1847 = 1914

Showing the first eight; more decompositions exist.
