Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664890, here are decompositions:

  • 19 + 8664871 = 8664890
  • 43 + 8664847 = 8664890
  • 103 + 8664787 = 8664890
  • 151 + 8664739 = 8664890
  • 229 + 8664661 = 8664890
  • 277 + 8664613 = 8664890
  • 331 + 8664559 = 8664890
  • 337 + 8664553 = 8664890

Showing the first eight; more decompositions exist.
