Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709778, here are decompositions:

  • 41 + 8709737 = 8709778
  • 47 + 8709731 = 8709778
  • 59 + 8709719 = 8709778
  • 101 + 8709677 = 8709778
  • 131 + 8709647 = 8709778
  • 167 + 8709611 = 8709778
  • 191 + 8709587 = 8709778
  • 251 + 8709527 = 8709778

Showing the first eight; more decompositions exist.
