Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443570, here are decompositions:

  • 3 + 2147443567 = 2147443570
  • 23 + 2147443547 = 2147443570
  • 47 + 2147443523 = 2147443570
  • 149 + 2147443421 = 2147443570
  • 179 + 2147443391 = 2147443570
  • 197 + 2147443373 = 2147443570
  • 227 + 2147443343 = 2147443570
  • 347 + 2147443223 = 2147443570

Showing the first eight; more decompositions exist.
