Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157938, here are decompositions:

  • 5 + 157933 = 157938
  • 7 + 157931 = 157938
  • 31 + 157907 = 157938
  • 37 + 157901 = 157938
  • 41 + 157897 = 157938
  • 61 + 157877 = 157938
  • 71 + 157867 = 157938
  • 97 + 157841 = 157938

Showing the first eight; more decompositions exist.
