Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426700, here are decompositions:

  • 7 + 2147426693 = 2147426700
  • 19 + 2147426681 = 2147426700
  • 31 + 2147426669 = 2147426700
  • 43 + 2147426657 = 2147426700
  • 59 + 2147426641 = 2147426700
  • 71 + 2147426629 = 2147426700
  • 127 + 2147426573 = 2147426700
  • 149 + 2147426551 = 2147426700

Showing the first eight; more decompositions exist.
