Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483390, here are decompositions:

  • 37 + 2147483353 = 2147483390
  • 67 + 2147483323 = 2147483390
  • 211 + 2147483179 = 2147483390
  • 313 + 2147483077 = 2147483390
  • 331 + 2147483059 = 2147483390
  • 337 + 2147483053 = 2147483390
  • 439 + 2147482951 = 2147483390
  • 523 + 2147482867 = 2147483390

Showing the first eight; more decompositions exist.
