Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429174, here are decompositions:

  • 43 + 2147429131 = 2147429174
  • 103 + 2147429071 = 2147429174
  • 127 + 2147429047 = 2147429174
  • 151 + 2147429023 = 2147429174
  • 193 + 2147428981 = 2147429174
  • 283 + 2147428891 = 2147429174
  • 313 + 2147428861 = 2147429174
  • 337 + 2147428837 = 2147429174

Showing the first eight; more decompositions exist.
