Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541378, here are decompositions:

  • 19 + 31541359 = 31541378
  • 31 + 31541347 = 31541378
  • 97 + 31541281 = 31541378
  • 109 + 31541269 = 31541378
  • 199 + 31541179 = 31541378
  • 277 + 31541101 = 31541378
  • 307 + 31541071 = 31541378
  • 331 + 31541047 = 31541378

Showing the first eight; more decompositions exist.
