Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429902, here are decompositions:

  • 5 + 2147429897 = 2147429902
  • 53 + 2147429849 = 2147429902
  • 269 + 2147429633 = 2147429902
  • 281 + 2147429621 = 2147429902
  • 461 + 2147429441 = 2147429902
  • 593 + 2147429309 = 2147429902
  • 719 + 2147429183 = 2147429902
  • 911 + 2147428991 = 2147429902

Showing the first eight; more decompositions exist.
