Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473390, here are decompositions:

  • 17 + 2147473373 = 2147473390
  • 59 + 2147473331 = 2147473390
  • 89 + 2147473301 = 2147473390
  • 107 + 2147473283 = 2147473390
  • 149 + 2147473241 = 2147473390
  • 173 + 2147473217 = 2147473390
  • 239 + 2147473151 = 2147473390
  • 263 + 2147473127 = 2147473390

Showing the first eight; more decompositions exist.
