Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482912, here are decompositions:

  • 53 + 2147482859 = 2147482912
  • 101 + 2147482811 = 2147482912
  • 149 + 2147482763 = 2147482912
  • 173 + 2147482739 = 2147482912
  • 251 + 2147482661 = 2147482912
  • 431 + 2147482481 = 2147482912
  • 503 + 2147482409 = 2147482912
  • 563 + 2147482349 = 2147482912

Showing the first eight; more decompositions exist.
