Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602152, here are decompositions:

  • 31 + 31602121 = 31602152
  • 73 + 31602079 = 31602152
  • 103 + 31602049 = 31602152
  • 229 + 31601923 = 31602152
  • 271 + 31601881 = 31602152
  • 409 + 31601743 = 31602152
  • 523 + 31601629 = 31602152
  • 601 + 31601551 = 31602152

Showing the first eight; more decompositions exist.
