Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429100, here are decompositions:

  • 29 + 2147429071 = 2147429100
  • 43 + 2147429057 = 2147429100
  • 53 + 2147429047 = 2147429100
  • 97 + 2147429003 = 2147429100
  • 101 + 2147428999 = 2147429100
  • 109 + 2147428991 = 2147429100
  • 151 + 2147428949 = 2147429100
  • 239 + 2147428861 = 2147429100

Showing the first eight; more decompositions exist.
