Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446494, here are decompositions:

  • 3 + 31446491 = 31446494
  • 67 + 31446427 = 31446494
  • 127 + 31446367 = 31446494
  • 241 + 31446253 = 31446494
  • 271 + 31446223 = 31446494
  • 283 + 31446211 = 31446494
  • 397 + 31446097 = 31446494
  • 433 + 31446061 = 31446494

Showing the first eight; more decompositions exist.
