Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680072, here are decompositions:

  • 29 + 8680043 = 8680072
  • 101 + 8679971 = 8680072
  • 173 + 8679899 = 8680072
  • 281 + 8679791 = 8680072
  • 431 + 8679641 = 8680072
  • 491 + 8679581 = 8680072
  • 521 + 8679551 = 8680072
  • 719 + 8679353 = 8680072

Showing the first eight; more decompositions exist.
