Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429952, here are decompositions:

  • 71 + 2147429881 = 2147429952
  • 89 + 2147429863 = 2147429952
  • 103 + 2147429849 = 2147429952
  • 113 + 2147429839 = 2147429952
  • 149 + 2147429803 = 2147429952
  • 263 + 2147429689 = 2147429952
  • 293 + 2147429659 = 2147429952
  • 331 + 2147429621 = 2147429952

Showing the first eight; more decompositions exist.
