Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492978, here are decompositions:

  • 11 + 492967 = 492978
  • 67 + 492911 = 492978
  • 107 + 492871 = 492978
  • 139 + 492839 = 492978
  • 179 + 492799 = 492978
  • 197 + 492781 = 492978
  • 257 + 492721 = 492978
  • 271 + 492707 = 492978

Showing the first eight; more decompositions exist.
