Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705442, here are decompositions:

  • 13 + 8705429 = 8705442
  • 23 + 8705419 = 8705442
  • 43 + 8705399 = 8705442
  • 59 + 8705383 = 8705442
  • 73 + 8705369 = 8705442
  • 131 + 8705311 = 8705442
  • 173 + 8705269 = 8705442
  • 181 + 8705261 = 8705442

Showing the first eight; more decompositions exist.
