Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147555308, here are decompositions:

  • 5 + 2147555303 = 2147555308
  • 29 + 2147555279 = 2147555308
  • 149 + 2147555159 = 2147555308
  • 191 + 2147555117 = 2147555308
  • 257 + 2147555051 = 2147555308
  • 281 + 2147555027 = 2147555308
  • 401 + 2147554907 = 2147555308
  • 461 + 2147554847 = 2147555308

Showing the first eight; more decompositions exist.
