Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295008640, here are decompositions:

  • 61 + 4295008579 = 4295008640
  • 67 + 4295008573 = 4295008640
  • 127 + 4295008513 = 4295008640
  • 157 + 4295008483 = 4295008640
  • 199 + 4295008441 = 4295008640
  • 283 + 4295008357 = 4295008640
  • 313 + 4295008327 = 4295008640
  • 337 + 4295008303 = 4295008640

Showing the first eight; more decompositions exist.
