Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592690, here are decompositions:

  • 7 + 31592683 = 31592690
  • 13 + 31592677 = 31592690
  • 139 + 31592551 = 31592690
  • 223 + 31592467 = 31592690
  • 313 + 31592377 = 31592690
  • 379 + 31592311 = 31592690
  • 433 + 31592257 = 31592690
  • 487 + 31592203 = 31592690

Showing the first eight; more decompositions exist.
