Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642010, here are decompositions:

  • 7 + 8642003 = 8642010
  • 19 + 8641991 = 8642010
  • 23 + 8641987 = 8642010
  • 53 + 8641957 = 8642010
  • 61 + 8641949 = 8642010
  • 101 + 8641909 = 8642010
  • 127 + 8641883 = 8642010
  • 137 + 8641873 = 8642010

Showing the first eight; more decompositions exist.
