Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602962, here are decompositions:

  • 3 + 31602959 = 31602962
  • 31 + 31602931 = 31602962
  • 103 + 31602859 = 31602962
  • 109 + 31602853 = 31602962
  • 199 + 31602763 = 31602962
  • 271 + 31602691 = 31602962
  • 283 + 31602679 = 31602962
  • 331 + 31602631 = 31602962

Showing the first eight; more decompositions exist.
