Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493516, here are decompositions:

  • 37 + 2147493479 = 2147493516
  • 59 + 2147493457 = 2147493516
  • 83 + 2147493433 = 2147493516
  • 107 + 2147493409 = 2147493516
  • 227 + 2147493289 = 2147493516
  • 239 + 2147493277 = 2147493516
  • 347 + 2147493169 = 2147493516
  • 397 + 2147493119 = 2147493516

Showing the first eight; more decompositions exist.
