Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624532, here are decompositions:

  • 103 + 31624429 = 31624532
  • 109 + 31624423 = 31624532
  • 193 + 31624339 = 31624532
  • 211 + 31624321 = 31624532
  • 463 + 31624069 = 31624532
  • 601 + 31623931 = 31624532
  • 631 + 31623901 = 31624532
  • 811 + 31623721 = 31624532

Showing the first eight; more decompositions exist.
