Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707642, here are decompositions:

  • 11 + 8707631 = 8707642
  • 263 + 8707379 = 8707642
  • 353 + 8707289 = 8707642
  • 401 + 8707241 = 8707642
  • 659 + 8706983 = 8707642
  • 761 + 8706881 = 8707642
  • 773 + 8706869 = 8707642
  • 809 + 8706833 = 8707642

Showing the first eight; more decompositions exist.
