Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482860, here are decompositions:

  • 41 + 2147482819 = 2147482860
  • 43 + 2147482817 = 2147482860
  • 59 + 2147482801 = 2147482860
  • 97 + 2147482763 = 2147482860
  • 163 + 2147482697 = 2147482860
  • 167 + 2147482693 = 2147482860
  • 179 + 2147482681 = 2147482860
  • 197 + 2147482663 = 2147482860

Showing the first eight; more decompositions exist.
