Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147375846, here are decompositions:

  • 73 + 2147375773 = 2147375846
  • 163 + 2147375683 = 2147375846
  • 277 + 2147375569 = 2147375846
  • 307 + 2147375539 = 2147375846
  • 337 + 2147375509 = 2147375846
  • 409 + 2147375437 = 2147375846
  • 433 + 2147375413 = 2147375846
  • 439 + 2147375407 = 2147375846

Showing the first eight; more decompositions exist.
