Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3620, here are decompositions:

  • 3 + 3617 = 3620
  • 7 + 3613 = 3620
  • 13 + 3607 = 3620
  • 37 + 3583 = 3620
  • 61 + 3559 = 3620
  • 73 + 3547 = 3620
  • 79 + 3541 = 3620
  • 103 + 3517 = 3620

Showing the first eight; more decompositions exist.
