Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147521282, here are decompositions:

  • 3 + 2147521279 = 2147521282
  • 41 + 2147521241 = 2147521282
  • 59 + 2147521223 = 2147521282
  • 83 + 2147521199 = 2147521282
  • 89 + 2147521193 = 2147521282
  • 191 + 2147521091 = 2147521282
  • 293 + 2147520989 = 2147521282
  • 443 + 2147520839 = 2147521282

Showing the first eight; more decompositions exist.
