Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469388, here are decompositions:

  • 41 + 2147469347 = 2147469388
  • 59 + 2147469329 = 2147469388
  • 149 + 2147469239 = 2147469388
  • 257 + 2147469131 = 2147469388
  • 347 + 2147469041 = 2147469388
  • 401 + 2147468987 = 2147469388
  • 479 + 2147468909 = 2147469388
  • 587 + 2147468801 = 2147469388

Showing the first eight; more decompositions exist.
