Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483442, here are decompositions:

  • 19 + 2147483423 = 2147483442
  • 43 + 2147483399 = 2147483442
  • 89 + 2147483353 = 2147483442
  • 173 + 2147483269 = 2147483442
  • 193 + 2147483249 = 2147483442
  • 263 + 2147483179 = 2147483442
  • 271 + 2147483171 = 2147483442
  • 373 + 2147483069 = 2147483442

Showing the first eight; more decompositions exist.
