Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1874, here are decompositions:

  • 3 + 1871 = 1874
  • 7 + 1867 = 1874
  • 13 + 1861 = 1874
  • 43 + 1831 = 1874
  • 73 + 1801 = 1874
  • 97 + 1777 = 1874
  • 127 + 1747 = 1874
  • 151 + 1723 = 1874

Showing the first eight; more decompositions exist.
