Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726890, here are decompositions:

  • 17 + 8726873 = 8726890
  • 41 + 8726849 = 8726890
  • 89 + 8726801 = 8726890
  • 101 + 8726789 = 8726890
  • 113 + 8726777 = 8726890
  • 131 + 8726759 = 8726890
  • 167 + 8726723 = 8726890
  • 191 + 8726699 = 8726890

Showing the first eight; more decompositions exist.
