Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443042, here are decompositions:

  • 29 + 2147443013 = 2147443042
  • 53 + 2147442989 = 2147443042
  • 149 + 2147442893 = 2147443042
  • 191 + 2147442851 = 2147443042
  • 233 + 2147442809 = 2147443042
  • 419 + 2147442623 = 2147443042
  • 743 + 2147442299 = 2147443042
  • 821 + 2147442221 = 2147443042

Showing the first eight; more decompositions exist.
