Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502266, here are decompositions:

  • 23 + 31502243 = 31502266
  • 53 + 31502213 = 31502266
  • 83 + 31502183 = 31502266
  • 137 + 31502129 = 31502266
  • 167 + 31502099 = 31502266
  • 353 + 31501913 = 31502266
  • 359 + 31501907 = 31502266
  • 443 + 31501823 = 31502266

Showing the first eight; more decompositions exist.
