Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480464, here are decompositions:

  • 23 + 31480441 = 31480464
  • 31 + 31480433 = 31480464
  • 73 + 31480391 = 31480464
  • 83 + 31480381 = 31480464
  • 97 + 31480367 = 31480464
  • 263 + 31480201 = 31480464
  • 347 + 31480117 = 31480464
  • 373 + 31480091 = 31480464

Showing the first eight; more decompositions exist.
