Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472272, here are decompositions:

  • 13 + 2147472259 = 2147472272
  • 73 + 2147472199 = 2147472272
  • 139 + 2147472133 = 2147472272
  • 163 + 2147472109 = 2147472272
  • 181 + 2147472091 = 2147472272
  • 229 + 2147472043 = 2147472272
  • 409 + 2147471863 = 2147472272
  • 433 + 2147471839 = 2147472272

Showing the first eight; more decompositions exist.
