Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527128, here are decompositions:

  • 19 + 31527109 = 31527128
  • 229 + 31526899 = 31527128
  • 337 + 31526791 = 31527128
  • 379 + 31526749 = 31527128
  • 397 + 31526731 = 31527128
  • 439 + 31526689 = 31527128
  • 601 + 31526527 = 31527128
  • 631 + 31526497 = 31527128

Showing the first eight; more decompositions exist.
