Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51888, here are decompositions:

  • 17 + 51871 = 51888
  • 19 + 51869 = 51888
  • 29 + 51859 = 51888
  • 59 + 51829 = 51888
  • 61 + 51827 = 51888
  • 71 + 51817 = 51888
  • 101 + 51787 = 51888
  • 139 + 51749 = 51888

Showing the first eight; more decompositions exist.
