Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493420, here are decompositions:

  • 11 + 2147493409 = 2147493420
  • 29 + 2147493391 = 2147493420
  • 109 + 2147493311 = 2147493420
  • 131 + 2147493289 = 2147493420
  • 139 + 2147493281 = 2147493420
  • 179 + 2147493241 = 2147493420
  • 251 + 2147493169 = 2147493420
  • 311 + 2147493109 = 2147493420

Showing the first eight; more decompositions exist.
