Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85378, here are decompositions:

  • 17 + 85361 = 85378
  • 47 + 85331 = 85378
  • 131 + 85247 = 85378
  • 149 + 85229 = 85378
  • 179 + 85199 = 85378
  • 257 + 85121 = 85378
  • 269 + 85109 = 85378
  • 317 + 85061 = 85378

Showing the first eight; more decompositions exist.
