Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66126, here are decompositions:

  • 17 + 66109 = 66126
  • 19 + 66107 = 66126
  • 23 + 66103 = 66126
  • 37 + 66089 = 66126
  • 43 + 66083 = 66126
  • 59 + 66067 = 66126
  • 79 + 66047 = 66126
  • 89 + 66037 = 66126

Showing the first eight; more decompositions exist.
