Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51972, here are decompositions:

  • 23 + 51949 = 51972
  • 31 + 51941 = 51972
  • 43 + 51929 = 51972
  • 59 + 51913 = 51972
  • 73 + 51899 = 51972
  • 79 + 51893 = 51972
  • 101 + 51871 = 51972
  • 103 + 51869 = 51972

Showing the first eight; more decompositions exist.
