Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527136, here are decompositions:

  • 5 + 31527131 = 31527136
  • 29 + 31527107 = 31527136
  • 59 + 31527077 = 31527136
  • 89 + 31527047 = 31527136
  • 197 + 31526939 = 31527136
  • 233 + 31526903 = 31527136
  • 257 + 31526879 = 31527136
  • 317 + 31526819 = 31527136

Showing the first eight; more decompositions exist.
