Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20010, here are decompositions:

  • 13 + 19997 = 20010
  • 17 + 19993 = 20010
  • 19 + 19991 = 20010
  • 31 + 19979 = 20010
  • 37 + 19973 = 20010
  • 47 + 19963 = 20010
  • 61 + 19949 = 20010
  • 73 + 19937 = 20010

Showing the first eight; more decompositions exist.
