Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532486, here are decompositions:

  • 157 + 31532329 = 31532486
  • 163 + 31532323 = 31532486
  • 277 + 31532209 = 31532486
  • 283 + 31532203 = 31532486
  • 373 + 31532113 = 31532486
  • 397 + 31532089 = 31532486
  • 577 + 31531909 = 31532486
  • 673 + 31531813 = 31532486

Showing the first eight; more decompositions exist.
