Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490830, here are decompositions:

  • 19 + 2147490811 = 2147490830
  • 31 + 2147490799 = 2147490830
  • 61 + 2147490769 = 2147490830
  • 103 + 2147490727 = 2147490830
  • 241 + 2147490589 = 2147490830
  • 367 + 2147490463 = 2147490830
  • 379 + 2147490451 = 2147490830
  • 487 + 2147490343 = 2147490830

Showing the first eight; more decompositions exist.
