Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665142, here are decompositions:

  • 19 + 8665123 = 8665142
  • 43 + 8665099 = 8665142
  • 103 + 8665039 = 8665142
  • 151 + 8664991 = 8665142
  • 163 + 8664979 = 8665142
  • 181 + 8664961 = 8665142
  • 193 + 8664949 = 8665142
  • 271 + 8664871 = 8665142

Showing the first eight; more decompositions exist.
