Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147562678, here are decompositions:

  • 7 + 2147562671 = 2147562678
  • 61 + 2147562617 = 2147562678
  • 67 + 2147562611 = 2147562678
  • 109 + 2147562569 = 2147562678
  • 127 + 2147562551 = 2147562678
  • 139 + 2147562539 = 2147562678
  • 167 + 2147562511 = 2147562678
  • 181 + 2147562497 = 2147562678

Showing the first eight; more decompositions exist.
