Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2576, here are decompositions:

  • 19 + 2557 = 2576
  • 37 + 2539 = 2576
  • 73 + 2503 = 2576
  • 103 + 2473 = 2576
  • 109 + 2467 = 2576
  • 139 + 2437 = 2576
  • 193 + 2383 = 2576
  • 199 + 2377 = 2576

Showing the first eight; more decompositions exist.
