Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499454, here are decompositions:

  • 3 + 2147499451 = 2147499454
  • 17 + 2147499437 = 2147499454
  • 41 + 2147499413 = 2147499454
  • 53 + 2147499401 = 2147499454
  • 131 + 2147499323 = 2147499454
  • 173 + 2147499281 = 2147499454
  • 293 + 2147499161 = 2147499454
  • 383 + 2147499071 = 2147499454

Showing the first eight; more decompositions exist.
