Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491558, here are decompositions:

  • 5 + 2147491553 = 2147491558
  • 11 + 2147491547 = 2147491558
  • 41 + 2147491517 = 2147491558
  • 197 + 2147491361 = 2147491558
  • 239 + 2147491319 = 2147491558
  • 281 + 2147491277 = 2147491558
  • 419 + 2147491139 = 2147491558
  • 431 + 2147491127 = 2147491558

Showing the first eight; more decompositions exist.
