Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1882, here are decompositions:

  • 3 + 1879 = 1882
  • 5 + 1877 = 1882
  • 11 + 1871 = 1882
  • 59 + 1823 = 1882
  • 71 + 1811 = 1882
  • 149 + 1733 = 1882
  • 173 + 1709 = 1882
  • 263 + 1619 = 1882

Showing the first eight; more decompositions exist.
