Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87976, here are decompositions:

  • 3 + 87973 = 87976
  • 17 + 87959 = 87976
  • 59 + 87917 = 87976
  • 89 + 87887 = 87976
  • 107 + 87869 = 87976
  • 173 + 87803 = 87976
  • 179 + 87797 = 87976
  • 233 + 87743 = 87976

Showing the first eight; more decompositions exist.
