Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147562642, here are decompositions:

  • 31 + 2147562611 = 2147562642
  • 73 + 2147562569 = 2147562642
  • 103 + 2147562539 = 2147562642
  • 131 + 2147562511 = 2147562642
  • 233 + 2147562409 = 2147562642
  • 263 + 2147562379 = 2147562642
  • 283 + 2147562359 = 2147562642
  • 311 + 2147562331 = 2147562642

Showing the first eight; more decompositions exist.
