Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147448180, here are decompositions:

  • 79 + 2147448101 = 2147448180
  • 89 + 2147448091 = 2147448180
  • 109 + 2147448071 = 2147448180
  • 131 + 2147448049 = 2147448180
  • 149 + 2147448031 = 2147448180
  • 167 + 2147448013 = 2147448180
  • 193 + 2147447987 = 2147448180
  • 263 + 2147447917 = 2147448180

Showing the first eight; more decompositions exist.
