Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639898, here are decompositions:

  • 61 + 8639837 = 8639898
  • 79 + 8639819 = 8639898
  • 89 + 8639809 = 8639898
  • 101 + 8639797 = 8639898
  • 149 + 8639749 = 8639898
  • 151 + 8639747 = 8639898
  • 251 + 8639647 = 8639898
  • 307 + 8639591 = 8639898

Showing the first eight; more decompositions exist.
