Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147481140, here are decompositions:

  • 109 + 2147481031 = 2147481140
  • 151 + 2147480989 = 2147481140
  • 199 + 2147480941 = 2147481140
  • 241 + 2147480899 = 2147481140
  • 349 + 2147480791 = 2147481140
  • 397 + 2147480743 = 2147481140
  • 433 + 2147480707 = 2147481140
  • 457 + 2147480683 = 2147481140

Showing the first eight; more decompositions exist.
