Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147530166, here are decompositions:

  • 157 + 2147530009 = 2147530166
  • 283 + 2147529883 = 2147530166
  • 307 + 2147529859 = 2147530166
  • 499 + 2147529667 = 2147530166
  • 709 + 2147529457 = 2147530166
  • 787 + 2147529379 = 2147530166
  • 937 + 2147529229 = 2147530166
  • 1093 + 2147529073 = 2147530166

Showing the first eight; more decompositions exist.
