Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446566, here are decompositions:

  • 3 + 31446563 = 31446566
  • 13 + 31446553 = 31446566
  • 127 + 31446439 = 31446566
  • 139 + 31446427 = 31446566
  • 199 + 31446367 = 31446566
  • 313 + 31446253 = 31446566
  • 337 + 31446229 = 31446566
  • 433 + 31446133 = 31446566

Showing the first eight; more decompositions exist.
