Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90256, here are decompositions:

  • 17 + 90239 = 90256
  • 29 + 90227 = 90256
  • 53 + 90203 = 90256
  • 59 + 90197 = 90256
  • 83 + 90173 = 90256
  • 107 + 90149 = 90256
  • 149 + 90107 = 90256
  • 167 + 90089 = 90256

Showing the first eight; more decompositions exist.
