Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90538, here are decompositions:

  • 5 + 90533 = 90538
  • 11 + 90527 = 90538
  • 101 + 90437 = 90538
  • 131 + 90407 = 90538
  • 137 + 90401 = 90538
  • 167 + 90371 = 90538
  • 179 + 90359 = 90538
  • 257 + 90281 = 90538

Showing the first eight; more decompositions exist.
