Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491740, here are decompositions:

  • 7 + 2147491733 = 2147491740
  • 41 + 2147491699 = 2147491740
  • 131 + 2147491609 = 2147491740
  • 137 + 2147491603 = 2147491740
  • 157 + 2147491583 = 2147491740
  • 167 + 2147491573 = 2147491740
  • 181 + 2147491559 = 2147491740
  • 193 + 2147491547 = 2147491740

Showing the first eight; more decompositions exist.
