Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147529842, here are decompositions:

  • 19 + 2147529823 = 2147529842
  • 79 + 2147529763 = 2147529842
  • 193 + 2147529649 = 2147529842
  • 463 + 2147529379 = 2147529842
  • 613 + 2147529229 = 2147529842
  • 691 + 2147529151 = 2147529842
  • 769 + 2147529073 = 2147529842
  • 811 + 2147529031 = 2147529842

Showing the first eight; more decompositions exist.
