Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147400056, here are decompositions:

  • 3 + 2147400053 = 2147400056
  • 73 + 2147399983 = 2147400056
  • 97 + 2147399959 = 2147400056
  • 337 + 2147399719 = 2147400056
  • 367 + 2147399689 = 2147400056
  • 463 + 2147399593 = 2147400056
  • 523 + 2147399533 = 2147400056
  • 547 + 2147399509 = 2147400056

Showing the first eight; more decompositions exist.
