Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732142, here are decompositions:

  • 5 + 8732137 = 8732142
  • 19 + 8732123 = 8732142
  • 61 + 8732081 = 8732142
  • 71 + 8732071 = 8732142
  • 113 + 8732029 = 8732142
  • 149 + 8731993 = 8732142
  • 151 + 8731991 = 8732142
  • 163 + 8731979 = 8732142

Showing the first eight; more decompositions exist.
