Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988528, here are decompositions:

  • 17 + 988511 = 988528
  • 89 + 988439 = 988528
  • 257 + 988271 = 988528
  • 311 + 988217 = 988528
  • 419 + 988109 = 988528
  • 461 + 988067 = 988528
  • 467 + 988061 = 988528
  • 521 + 988007 = 988528

Showing the first eight; more decompositions exist.
