Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2442, here are decompositions:

  • 5 + 2437 = 2442
  • 19 + 2423 = 2442
  • 31 + 2411 = 2442
  • 43 + 2399 = 2442
  • 53 + 2389 = 2442
  • 59 + 2383 = 2442
  • 61 + 2381 = 2442
  • 71 + 2371 = 2442

Showing the first eight; more decompositions exist.
