Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739880, here are decompositions:

  • 3 + 8739877 = 8739880
  • 11 + 8739869 = 8739880
  • 29 + 8739851 = 8739880
  • 53 + 8739827 = 8739880
  • 59 + 8739821 = 8739880
  • 113 + 8739767 = 8739880
  • 131 + 8739749 = 8739880
  • 167 + 8739713 = 8739880

Showing the first eight; more decompositions exist.
