Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531608, here are decompositions:

  • 19 + 531589 = 531608
  • 37 + 531571 = 531608
  • 61 + 531547 = 531608
  • 127 + 531481 = 531608
  • 151 + 531457 = 531608
  • 271 + 531337 = 531608
  • 277 + 531331 = 531608
  • 379 + 531229 = 531608

Showing the first eight; more decompositions exist.
