Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55530, here are decompositions:

  • 19 + 55511 = 55530
  • 29 + 55501 = 55530
  • 43 + 55487 = 55530
  • 61 + 55469 = 55530
  • 73 + 55457 = 55530
  • 89 + 55441 = 55530
  • 131 + 55399 = 55530
  • 149 + 55381 = 55530

Showing the first eight; more decompositions exist.
