Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532906, here are decompositions:

  • 7 + 31532899 = 31532906
  • 43 + 31532863 = 31532906
  • 73 + 31532833 = 31532906
  • 157 + 31532749 = 31532906
  • 313 + 31532593 = 31532906
  • 367 + 31532539 = 31532906
  • 409 + 31532497 = 31532906
  • 577 + 31532329 = 31532906

Showing the first eight; more decompositions exist.
