Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472422, here are decompositions:

  • 71 + 31472351 = 31472422
  • 83 + 31472339 = 31472422
  • 131 + 31472291 = 31472422
  • 239 + 31472183 = 31472422
  • 263 + 31472159 = 31472422
  • 269 + 31472153 = 31472422
  • 353 + 31472069 = 31472422
  • 419 + 31472003 = 31472422

Showing the first eight; more decompositions exist.
