Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623454, here are decompositions:

  • 11 + 31623443 = 31623454
  • 197 + 31623257 = 31623454
  • 281 + 31623173 = 31623454
  • 431 + 31623023 = 31623454
  • 503 + 31622951 = 31623454
  • 521 + 31622933 = 31623454
  • 617 + 31622837 = 31623454
  • 677 + 31622777 = 31623454

Showing the first eight; more decompositions exist.
