Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526684, here are decompositions:

  • 37 + 31526647 = 31526684
  • 67 + 31526617 = 31526684
  • 151 + 31526533 = 31526684
  • 157 + 31526527 = 31526684
  • 181 + 31526503 = 31526684
  • 313 + 31526371 = 31526684
  • 367 + 31526317 = 31526684
  • 457 + 31526227 = 31526684

Showing the first eight; more decompositions exist.
