Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541946, here are decompositions:

  • 13 + 31541933 = 31541946
  • 43 + 31541903 = 31541946
  • 47 + 31541899 = 31541946
  • 53 + 31541893 = 31541946
  • 89 + 31541857 = 31541946
  • 239 + 31541707 = 31541946
  • 269 + 31541677 = 31541946
  • 313 + 31541633 = 31541946

Showing the first eight; more decompositions exist.
