Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51900, here are decompositions:

  • 7 + 51893 = 51900
  • 29 + 51871 = 51900
  • 31 + 51869 = 51900
  • 41 + 51859 = 51900
  • 47 + 51853 = 51900
  • 61 + 51839 = 51900
  • 71 + 51829 = 51900
  • 73 + 51827 = 51900

Showing the first eight; more decompositions exist.
