Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725886, here are decompositions:

  • 73 + 8725813 = 8725886
  • 229 + 8725657 = 8725886
  • 277 + 8725609 = 8725886
  • 397 + 8725489 = 8725886
  • 457 + 8725429 = 8725886
  • 487 + 8725399 = 8725886
  • 523 + 8725363 = 8725886
  • 607 + 8725279 = 8725886

Showing the first eight; more decompositions exist.
