Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473038, here are decompositions:

  • 79 + 2147472959 = 2147473038
  • 241 + 2147472797 = 2147473038
  • 251 + 2147472787 = 2147473038
  • 281 + 2147472757 = 2147473038
  • 349 + 2147472689 = 2147473038
  • 379 + 2147472659 = 2147473038
  • 421 + 2147472617 = 2147473038
  • 547 + 2147472491 = 2147473038

Showing the first eight; more decompositions exist.
