Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580254, here are decompositions:

  • 23 + 31580231 = 31580254
  • 47 + 31580207 = 31580254
  • 71 + 31580183 = 31580254
  • 191 + 31580063 = 31580254
  • 197 + 31580057 = 31580254
  • 401 + 31579853 = 31580254
  • 491 + 31579763 = 31580254
  • 593 + 31579661 = 31580254

Showing the first eight; more decompositions exist.
