Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990584, here are decompositions:

  • 37 + 990547 = 990584
  • 61 + 990523 = 990584
  • 73 + 990511 = 990584
  • 97 + 990487 = 990584
  • 223 + 990361 = 990584
  • 271 + 990313 = 990584
  • 277 + 990307 = 990584
  • 307 + 990277 = 990584

Showing the first eight; more decompositions exist.
