Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404282, here are decompositions:

  • 53 + 2147404229 = 2147404282
  • 71 + 2147404211 = 2147404282
  • 251 + 2147404031 = 2147404282
  • 263 + 2147404019 = 2147404282
  • 281 + 2147404001 = 2147404282
  • 389 + 2147403893 = 2147404282
  • 503 + 2147403779 = 2147404282
  • 563 + 2147403719 = 2147404282

Showing the first eight; more decompositions exist.
