Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71570, here are decompositions:

  • 7 + 71563 = 71570
  • 19 + 71551 = 71570
  • 43 + 71527 = 71570
  • 67 + 71503 = 71570
  • 97 + 71473 = 71570
  • 127 + 71443 = 71570
  • 151 + 71419 = 71570
  • 157 + 71413 = 71570

Showing the first eight; more decompositions exist.
