Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443442, here are decompositions:

  • 19 + 2147443423 = 2147443442
  • 31 + 2147443411 = 2147443442
  • 43 + 2147443399 = 2147443442
  • 103 + 2147443339 = 2147443442
  • 139 + 2147443303 = 2147443442
  • 271 + 2147443171 = 2147443442
  • 409 + 2147443033 = 2147443442
  • 421 + 2147443021 = 2147443442

Showing the first eight; more decompositions exist.
