Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987748, here are decompositions:

  • 89 + 987659 = 987748
  • 149 + 987599 = 987748
  • 239 + 987509 = 987748
  • 257 + 987491 = 987748
  • 449 + 987299 = 987748
  • 521 + 987227 = 987748
  • 557 + 987191 = 987748
  • 647 + 987101 = 987748

Showing the first eight; more decompositions exist.
