Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78486, here are decompositions:

  • 7 + 78479 = 78486
  • 19 + 78467 = 78486
  • 47 + 78439 = 78486
  • 59 + 78427 = 78486
  • 139 + 78347 = 78486
  • 179 + 78307 = 78486
  • 227 + 78259 = 78486
  • 257 + 78229 = 78486

Showing the first eight; more decompositions exist.
