Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147379484, here are decompositions:

  • 11 + 2147379473 = 2147379484
  • 53 + 2147379431 = 2147379484
  • 641 + 2147378843 = 2147379484
  • 647 + 2147378837 = 2147379484
  • 983 + 2147378501 = 2147379484
  • 1091 + 2147378393 = 2147379484
  • 1103 + 2147378381 = 2147379484
  • 1187 + 2147378297 = 2147379484

Showing the first eight; more decompositions exist.
