Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472260, here are decompositions:

  • 61 + 2147472199 = 2147472260
  • 127 + 2147472133 = 2147472260
  • 151 + 2147472109 = 2147472260
  • 223 + 2147472037 = 2147472260
  • 379 + 2147471881 = 2147472260
  • 397 + 2147471863 = 2147472260
  • 421 + 2147471839 = 2147472260
  • 613 + 2147471647 = 2147472260

Showing the first eight; more decompositions exist.
