Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89990, here are decompositions:

  • 7 + 89983 = 89990
  • 13 + 89977 = 89990
  • 31 + 89959 = 89990
  • 67 + 89923 = 89990
  • 73 + 89917 = 89990
  • 151 + 89839 = 89990
  • 157 + 89833 = 89990
  • 181 + 89809 = 89990

Showing the first eight; more decompositions exist.
