Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466840, here are decompositions:

  • 7 + 2147466833 = 2147466840
  • 47 + 2147466793 = 2147466840
  • 53 + 2147466787 = 2147466840
  • 139 + 2147466701 = 2147466840
  • 157 + 2147466683 = 2147466840
  • 199 + 2147466641 = 2147466840
  • 251 + 2147466589 = 2147466840
  • 293 + 2147466547 = 2147466840

Showing the first eight; more decompositions exist.
