Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691086, here are decompositions:

  • 43 + 8691043 = 8691086
  • 67 + 8691019 = 8691086
  • 127 + 8690959 = 8691086
  • 139 + 8690947 = 8691086
  • 373 + 8690713 = 8691086
  • 409 + 8690677 = 8691086
  • 487 + 8690599 = 8691086
  • 673 + 8690413 = 8691086

Showing the first eight; more decompositions exist.
