Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635490, here are decompositions:

  • 13 + 8635477 = 8635490
  • 67 + 8635423 = 8635490
  • 109 + 8635381 = 8635490
  • 139 + 8635351 = 8635490
  • 211 + 8635279 = 8635490
  • 229 + 8635261 = 8635490
  • 271 + 8635219 = 8635490
  • 349 + 8635141 = 8635490

Showing the first eight; more decompositions exist.
