Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482978, here are decompositions:

  • 29 + 2147482949 = 2147482978
  • 41 + 2147482937 = 2147482978
  • 101 + 2147482877 = 2147482978
  • 167 + 2147482811 = 2147482978
  • 239 + 2147482739 = 2147482978
  • 281 + 2147482697 = 2147482978
  • 317 + 2147482661 = 2147482978
  • 401 + 2147482577 = 2147482978

Showing the first eight; more decompositions exist.
