Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501902, here are decompositions:

  • 233 + 2147501669 = 2147501902
  • 383 + 2147501519 = 2147501902
  • 599 + 2147501303 = 2147501902
  • 653 + 2147501249 = 2147501902
  • 773 + 2147501129 = 2147501902
  • 971 + 2147500931 = 2147501902
  • 1013 + 2147500889 = 2147501902
  • 1031 + 2147500871 = 2147501902

Showing the first eight; more decompositions exist.
