Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89778, here are decompositions:

  • 11 + 89767 = 89778
  • 19 + 89759 = 89778
  • 89 + 89689 = 89778
  • 97 + 89681 = 89778
  • 107 + 89671 = 89778
  • 109 + 89669 = 89778
  • 151 + 89627 = 89778
  • 167 + 89611 = 89778

Showing the first eight; more decompositions exist.
