Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498166, here are decompositions:

  • 19 + 2147498147 = 2147498166
  • 89 + 2147498077 = 2147498166
  • 223 + 2147497943 = 2147498166
  • 227 + 2147497939 = 2147498166
  • 277 + 2147497889 = 2147498166
  • 397 + 2147497769 = 2147498166
  • 409 + 2147497757 = 2147498166
  • 433 + 2147497733 = 2147498166

Showing the first eight; more decompositions exist.
