Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527600, here are decompositions:

  • 17 + 31527583 = 31527600
  • 23 + 31527577 = 31527600
  • 31 + 31527569 = 31527600
  • 59 + 31527541 = 31527600
  • 67 + 31527533 = 31527600
  • 79 + 31527521 = 31527600
  • 101 + 31527499 = 31527600
  • 103 + 31527497 = 31527600

Showing the first eight; more decompositions exist.
