Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429932, here are decompositions:

  • 83 + 2147429849 = 2147429932
  • 311 + 2147429621 = 2147429932
  • 491 + 2147429441 = 2147429932
  • 569 + 2147429363 = 2147429932
  • 719 + 2147429213 = 2147429932
  • 929 + 2147429003 = 2147429932
  • 941 + 2147428991 = 2147429932
  • 983 + 2147428949 = 2147429932

Showing the first eight; more decompositions exist.
