Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446050, here are decompositions:

  • 19 + 31446031 = 31446050
  • 67 + 31445983 = 31446050
  • 73 + 31445977 = 31446050
  • 109 + 31445941 = 31446050
  • 199 + 31445851 = 31446050
  • 331 + 31445719 = 31446050
  • 373 + 31445677 = 31446050
  • 409 + 31445641 = 31446050

Showing the first eight; more decompositions exist.
