Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461562, here are decompositions:

  • 5 + 31461557 = 31461562
  • 29 + 31461533 = 31461562
  • 149 + 31461413 = 31461562
  • 269 + 31461293 = 31461562
  • 281 + 31461281 = 31461562
  • 383 + 31461179 = 31461562
  • 389 + 31461173 = 31461562
  • 401 + 31461161 = 31461562

Showing the first eight; more decompositions exist.
