Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489638, here are decompositions:

  • 59 + 2147489579 = 2147489638
  • 101 + 2147489537 = 2147489638
  • 197 + 2147489441 = 2147489638
  • 347 + 2147489291 = 2147489638
  • 431 + 2147489207 = 2147489638
  • 641 + 2147488997 = 2147489638
  • 719 + 2147488919 = 2147489638
  • 887 + 2147488751 = 2147489638

Showing the first eight; more decompositions exist.
