Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499508, here are decompositions:

  • 29 + 2147499479 = 2147499508
  • 47 + 2147499461 = 2147499508
  • 71 + 2147499437 = 2147499508
  • 107 + 2147499401 = 2147499508
  • 197 + 2147499311 = 2147499508
  • 227 + 2147499281 = 2147499508
  • 347 + 2147499161 = 2147499508
  • 389 + 2147499119 = 2147499508

Showing the first eight; more decompositions exist.
