Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491722, here are decompositions:

  • 23 + 2147491699 = 2147491722
  • 31 + 2147491691 = 2147491722
  • 113 + 2147491609 = 2147491722
  • 139 + 2147491583 = 2147491722
  • 149 + 2147491573 = 2147491722
  • 163 + 2147491559 = 2147491722
  • 179 + 2147491543 = 2147491722
  • 353 + 2147491369 = 2147491722

Showing the first eight; more decompositions exist.
