Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449910, here are decompositions:

  • 263 + 31449647 = 31449910
  • 281 + 31449629 = 31449910
  • 353 + 31449557 = 31449910
  • 383 + 31449527 = 31449910
  • 431 + 31449479 = 31449910
  • 461 + 31449449 = 31449910
  • 509 + 31449401 = 31449910
  • 587 + 31449323 = 31449910

Showing the first eight; more decompositions exist.
