Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482388, here are decompositions:

  • 61 + 2147482327 = 2147482388
  • 97 + 2147482291 = 2147482388
  • 151 + 2147482237 = 2147482388
  • 157 + 2147482231 = 2147482388
  • 307 + 2147482081 = 2147482388
  • 367 + 2147482021 = 2147482388
  • 421 + 2147481967 = 2147482388
  • 439 + 2147481949 = 2147482388

Showing the first eight; more decompositions exist.
