Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603732, here are decompositions:

  • 11 + 31603721 = 31603732
  • 23 + 31603709 = 31603732
  • 89 + 31603643 = 31603732
  • 179 + 31603553 = 31603732
  • 389 + 31603343 = 31603732
  • 593 + 31603139 = 31603732
  • 653 + 31603079 = 31603732
  • 659 + 31603073 = 31603732

Showing the first eight; more decompositions exist.
