Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89018, here are decompositions:

  • 67 + 88951 = 89018
  • 151 + 88867 = 89018
  • 157 + 88861 = 89018
  • 199 + 88819 = 89018
  • 211 + 88807 = 89018
  • 229 + 88789 = 89018
  • 271 + 88747 = 89018
  • 277 + 88741 = 89018

Showing the first eight; more decompositions exist.
