Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77256, here are decompositions:

  • 7 + 77249 = 77256
  • 13 + 77243 = 77256
  • 17 + 77239 = 77256
  • 19 + 77237 = 77256
  • 43 + 77213 = 77256
  • 89 + 77167 = 77256
  • 103 + 77153 = 77256
  • 163 + 77093 = 77256

Showing the first eight; more decompositions exist.
