Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473630, here are decompositions:

  • 257 + 2147473373 = 2147473630
  • 347 + 2147473283 = 2147473630
  • 389 + 2147473241 = 2147473630
  • 443 + 2147473187 = 2147473630
  • 479 + 2147473151 = 2147473630
  • 503 + 2147473127 = 2147473630
  • 509 + 2147473121 = 2147473630
  • 569 + 2147473061 = 2147473630

Showing the first eight; more decompositions exist.
