Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627552, here are decompositions:

  • 41 + 31627511 = 31627552
  • 179 + 31627373 = 31627552
  • 233 + 31627319 = 31627552
  • 263 + 31627289 = 31627552
  • 401 + 31627151 = 31627552
  • 419 + 31627133 = 31627552
  • 431 + 31627121 = 31627552
  • 461 + 31627091 = 31627552

Showing the first eight; more decompositions exist.
