Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147529854, here are decompositions:

  • 31 + 2147529823 = 2147529854
  • 103 + 2147529751 = 2147529854
  • 181 + 2147529673 = 2147529854
  • 397 + 2147529457 = 2147529854
  • 523 + 2147529331 = 2147529854
  • 577 + 2147529277 = 2147529854
  • 733 + 2147529121 = 2147529854
  • 823 + 2147529031 = 2147529854

Showing the first eight; more decompositions exist.
