Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71518, here are decompositions:

  • 47 + 71471 = 71518
  • 89 + 71429 = 71518
  • 107 + 71411 = 71518
  • 131 + 71387 = 71518
  • 179 + 71339 = 71518
  • 191 + 71327 = 71518
  • 257 + 71261 = 71518
  • 269 + 71249 = 71518

Showing the first eight; more decompositions exist.
