Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736890, here are decompositions:

  • 7 + 8736883 = 8736890
  • 37 + 8736853 = 8736890
  • 73 + 8736817 = 8736890
  • 103 + 8736787 = 8736890
  • 109 + 8736781 = 8736890
  • 163 + 8736727 = 8736890
  • 223 + 8736667 = 8736890
  • 307 + 8736583 = 8736890

Showing the first eight; more decompositions exist.
