Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86278, here are decompositions:

  • 29 + 86249 = 86278
  • 107 + 86171 = 86278
  • 167 + 86111 = 86278
  • 251 + 86027 = 86278
  • 347 + 85931 = 86278
  • 389 + 85889 = 86278
  • 431 + 85847 = 86278
  • 449 + 85829 = 86278

Showing the first eight; more decompositions exist.
