Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147560420, here are decompositions:

  • 41 + 2147560379 = 2147560420
  • 101 + 2147560319 = 2147560420
  • 227 + 2147560193 = 2147560420
  • 263 + 2147560157 = 2147560420
  • 293 + 2147560127 = 2147560420
  • 311 + 2147560109 = 2147560420
  • 431 + 2147559989 = 2147560420
  • 443 + 2147559977 = 2147560420

Showing the first eight; more decompositions exist.
