Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987892, here are decompositions:

  • 23 + 987869 = 987892
  • 41 + 987851 = 987892
  • 71 + 987821 = 987892
  • 83 + 987809 = 987892
  • 89 + 987803 = 987892
  • 179 + 987713 = 987892
  • 233 + 987659 = 987892
  • 293 + 987599 = 987892

Showing the first eight; more decompositions exist.
