Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482872, here are decompositions:

  • 5 + 2147482867 = 2147482872
  • 13 + 2147482859 = 2147482872
  • 53 + 2147482819 = 2147482872
  • 61 + 2147482811 = 2147482872
  • 71 + 2147482801 = 2147482872
  • 109 + 2147482763 = 2147482872
  • 179 + 2147482693 = 2147482872
  • 191 + 2147482681 = 2147482872

Showing the first eight; more decompositions exist.
