Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453190, here are decompositions:

  • 19 + 31453171 = 31453190
  • 31 + 31453159 = 31453190
  • 151 + 31453039 = 31453190
  • 331 + 31452859 = 31453190
  • 397 + 31452793 = 31453190
  • 421 + 31452769 = 31453190
  • 463 + 31452727 = 31453190
  • 523 + 31452667 = 31453190

Showing the first eight; more decompositions exist.
