Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467618, here are decompositions:

  • 59 + 2147467559 = 2147467618
  • 239 + 2147467379 = 2147467618
  • 251 + 2147467367 = 2147467618
  • 449 + 2147467169 = 2147467618
  • 977 + 2147466641 = 2147467618
  • 1097 + 2147466521 = 2147467618
  • 1259 + 2147466359 = 2147467618
  • 1289 + 2147466329 = 2147467618

Showing the first eight; more decompositions exist.
