Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147428258, here are decompositions:

  • 149 + 2147428109 = 2147428258
  • 347 + 2147427911 = 2147428258
  • 419 + 2147427839 = 2147428258
  • 431 + 2147427827 = 2147428258
  • 461 + 2147427797 = 2147428258
  • 557 + 2147427701 = 2147428258
  • 1049 + 2147427209 = 2147428258
  • 1217 + 2147427041 = 2147428258

Showing the first eight; more decompositions exist.
