Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747584, here are decompositions:

  • 5 + 8747579 = 8747584
  • 11 + 8747573 = 8747584
  • 23 + 8747561 = 8747584
  • 71 + 8747513 = 8747584
  • 101 + 8747483 = 8747584
  • 113 + 8747471 = 8747584
  • 257 + 8747327 = 8747584
  • 311 + 8747273 = 8747584

Showing the first eight; more decompositions exist.
