Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491420, here are decompositions:

  • 3 + 2147491417 = 2147491420
  • 17 + 2147491403 = 2147491420
  • 59 + 2147491361 = 2147491420
  • 71 + 2147491349 = 2147491420
  • 101 + 2147491319 = 2147491420
  • 197 + 2147491223 = 2147491420
  • 227 + 2147491193 = 2147491420
  • 281 + 2147491139 = 2147491420

Showing the first eight; more decompositions exist.
