Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542704, here are decompositions:

  • 7 + 31542697 = 31542704
  • 73 + 31542631 = 31542704
  • 157 + 31542547 = 31542704
  • 181 + 31542523 = 31542704
  • 307 + 31542397 = 31542704
  • 313 + 31542391 = 31542704
  • 331 + 31542373 = 31542704
  • 541 + 31542163 = 31542704

Showing the first eight; more decompositions exist.
