Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727988, here are decompositions:

  • 89 + 8727899 = 8727988
  • 131 + 8727857 = 8727988
  • 179 + 8727809 = 8727988
  • 197 + 8727791 = 8727988
  • 257 + 8727731 = 8727988
  • 389 + 8727599 = 8727988
  • 419 + 8727569 = 8727988
  • 449 + 8727539 = 8727988

Showing the first eight; more decompositions exist.
