Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489538, here are decompositions:

  • 97 + 2147489441 = 2147489538
  • 101 + 2147489437 = 2147489538
  • 137 + 2147489401 = 2147489538
  • 191 + 2147489347 = 2147489538
  • 239 + 2147489299 = 2147489538
  • 241 + 2147489297 = 2147489538
  • 331 + 2147489207 = 2147489538
  • 449 + 2147489089 = 2147489538

Showing the first eight; more decompositions exist.
