Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469578, here are decompositions:

  • 157 + 2147469421 = 2147469578
  • 307 + 2147469271 = 2147469578
  • 349 + 2147469229 = 2147469578
  • 421 + 2147469157 = 2147469578
  • 571 + 2147469007 = 2147469578
  • 577 + 2147469001 = 2147469578
  • 607 + 2147468971 = 2147469578
  • 691 + 2147468887 = 2147469578

Showing the first eight; more decompositions exist.
