Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65990, here are decompositions:

  • 7 + 65983 = 65990
  • 61 + 65929 = 65990
  • 109 + 65881 = 65990
  • 139 + 65851 = 65990
  • 151 + 65839 = 65990
  • 163 + 65827 = 65990
  • 181 + 65809 = 65990
  • 229 + 65761 = 65990

Showing the first eight; more decompositions exist.
