Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592954, here are decompositions:

  • 7 + 31592947 = 31592954
  • 31 + 31592923 = 31592954
  • 157 + 31592797 = 31592954
  • 181 + 31592773 = 31592954
  • 193 + 31592761 = 31592954
  • 271 + 31592683 = 31592954
  • 277 + 31592677 = 31592954
  • 313 + 31592641 = 31592954

Showing the first eight; more decompositions exist.
