Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485520, here are decompositions:

  • 3 + 2147485517 = 2147485520
  • 73 + 2147485447 = 2147485520
  • 97 + 2147485423 = 2147485520
  • 109 + 2147485411 = 2147485520
  • 139 + 2147485381 = 2147485520
  • 151 + 2147485369 = 2147485520
  • 163 + 2147485357 = 2147485520
  • 211 + 2147485309 = 2147485520

Showing the first eight; more decompositions exist.
