Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429752, here are decompositions:

  • 131 + 2147429621 = 2147429752
  • 191 + 2147429561 = 2147429752
  • 311 + 2147429441 = 2147429752
  • 389 + 2147429363 = 2147429752
  • 401 + 2147429351 = 2147429752
  • 443 + 2147429309 = 2147429752
  • 569 + 2147429183 = 2147429752
  • 761 + 2147428991 = 2147429752

Showing the first eight; more decompositions exist.
