Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4542, here are decompositions:

  • 19 + 4523 = 4542
  • 23 + 4519 = 4542
  • 29 + 4513 = 4542
  • 59 + 4483 = 4542
  • 61 + 4481 = 4542
  • 79 + 4463 = 4542
  • 101 + 4441 = 4542
  • 151 + 4391 = 4542

Showing the first eight; more decompositions exist.
