Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499982, here are decompositions:

  • 29 + 2147499953 = 2147499982
  • 59 + 2147499923 = 2147499982
  • 311 + 2147499671 = 2147499982
  • 443 + 2147499539 = 2147499982
  • 449 + 2147499533 = 2147499982
  • 461 + 2147499521 = 2147499982
  • 503 + 2147499479 = 2147499982
  • 521 + 2147499461 = 2147499982

Showing the first eight; more decompositions exist.
