Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526300, here are decompositions:

  • 19 + 31526281 = 31526300
  • 61 + 31526239 = 31526300
  • 73 + 31526227 = 31526300
  • 79 + 31526221 = 31526300
  • 103 + 31526197 = 31526300
  • 109 + 31526191 = 31526300
  • 349 + 31525951 = 31526300
  • 373 + 31525927 = 31526300

Showing the first eight; more decompositions exist.
