Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78442, here are decompositions:

  • 3 + 78439 = 78442
  • 5 + 78437 = 78442
  • 41 + 78401 = 78442
  • 101 + 78341 = 78442
  • 131 + 78311 = 78442
  • 239 + 78203 = 78442
  • 251 + 78191 = 78442
  • 263 + 78179 = 78442

Showing the first eight; more decompositions exist.
