Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473544, here are decompositions:

  • 107 + 31473437 = 31473544
  • 131 + 31473413 = 31473544
  • 281 + 31473263 = 31473544
  • 293 + 31473251 = 31473544
  • 353 + 31473191 = 31473544
  • 383 + 31473161 = 31473544
  • 461 + 31473083 = 31473544
  • 467 + 31473077 = 31473544

Showing the first eight; more decompositions exist.
