Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473220, here are decompositions:

  • 3 + 2147473217 = 2147473220
  • 103 + 2147473117 = 2147473220
  • 337 + 2147472883 = 2147473220
  • 433 + 2147472787 = 2147473220
  • 463 + 2147472757 = 2147473220
  • 523 + 2147472697 = 2147473220
  • 619 + 2147472601 = 2147473220
  • 751 + 2147472469 = 2147473220

Showing the first eight; more decompositions exist.
