Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446544, here are decompositions:

  • 11 + 31446533 = 31446544
  • 53 + 31446491 = 31446544
  • 83 + 31446461 = 31446544
  • 293 + 31446251 = 31446544
  • 317 + 31446227 = 31446544
  • 443 + 31446101 = 31446544
  • 491 + 31446053 = 31446544
  • 587 + 31445957 = 31446544

Showing the first eight; more decompositions exist.
