Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703820, here are decompositions:

  • 3 + 8703817 = 8703820
  • 101 + 8703719 = 8703820
  • 179 + 8703641 = 8703820
  • 197 + 8703623 = 8703820
  • 227 + 8703593 = 8703820
  • 239 + 8703581 = 8703820
  • 269 + 8703551 = 8703820
  • 431 + 8703389 = 8703820

Showing the first eight; more decompositions exist.
