Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489844, here are decompositions:

  • 23 + 2147489821 = 2147489844
  • 47 + 2147489797 = 2147489844
  • 127 + 2147489717 = 2147489844
  • 131 + 2147489713 = 2147489844
  • 191 + 2147489653 = 2147489844
  • 193 + 2147489651 = 2147489844
  • 257 + 2147489587 = 2147489844
  • 307 + 2147489537 = 2147489844

Showing the first eight; more decompositions exist.
