Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98990, here are decompositions:

  • 37 + 98953 = 98990
  • 43 + 98947 = 98990
  • 61 + 98929 = 98990
  • 79 + 98911 = 98990
  • 97 + 98893 = 98990
  • 103 + 98887 = 98990
  • 181 + 98809 = 98990
  • 211 + 98779 = 98990

Showing the first eight; more decompositions exist.
