Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541698, here are decompositions:

  • 5 + 31541693 = 31541698
  • 47 + 31541651 = 31541698
  • 101 + 31541597 = 31541698
  • 107 + 31541591 = 31541698
  • 191 + 31541507 = 31541698
  • 269 + 31541429 = 31541698
  • 281 + 31541417 = 31541698
  • 401 + 31541297 = 31541698

Showing the first eight; more decompositions exist.
