Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666272, here are decompositions:

  • 3 + 8666269 = 8666272
  • 53 + 8666219 = 8666272
  • 71 + 8666201 = 8666272
  • 89 + 8666183 = 8666272
  • 113 + 8666159 = 8666272
  • 179 + 8666093 = 8666272
  • 281 + 8665991 = 8666272
  • 359 + 8665913 = 8666272

Showing the first eight; more decompositions exist.
