Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90480, here are decompositions:

  • 7 + 90473 = 90480
  • 11 + 90469 = 90480
  • 41 + 90439 = 90480
  • 43 + 90437 = 90480
  • 73 + 90407 = 90480
  • 79 + 90401 = 90480
  • 83 + 90397 = 90480
  • 101 + 90379 = 90480

Showing the first eight; more decompositions exist.
