Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422100, here are decompositions:

  • 3 + 2147422097 = 2147422100
  • 13 + 2147422087 = 2147422100
  • 37 + 2147422063 = 2147422100
  • 67 + 2147422033 = 2147422100
  • 193 + 2147421907 = 2147422100
  • 331 + 2147421769 = 2147422100
  • 379 + 2147421721 = 2147422100
  • 619 + 2147421481 = 2147422100

Showing the first eight; more decompositions exist.
