Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147456952, here are decompositions:

  • 23 + 2147456929 = 2147456952
  • 29 + 2147456923 = 2147456952
  • 41 + 2147456911 = 2147456952
  • 73 + 2147456879 = 2147456952
  • 83 + 2147456869 = 2147456952
  • 163 + 2147456789 = 2147456952
  • 269 + 2147456683 = 2147456952
  • 271 + 2147456681 = 2147456952

Showing the first eight; more decompositions exist.
