Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147476238, here are decompositions:

  • 97 + 2147476141 = 2147476238
  • 151 + 2147476087 = 2147476238
  • 241 + 2147475997 = 2147476238
  • 367 + 2147475871 = 2147476238
  • 379 + 2147475859 = 2147476238
  • 409 + 2147475829 = 2147476238
  • 499 + 2147475739 = 2147476238
  • 547 + 2147475691 = 2147476238

Showing the first eight; more decompositions exist.
