Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525942, here are decompositions:

  • 23 + 31525919 = 31525942
  • 29 + 31525913 = 31525942
  • 53 + 31525889 = 31525942
  • 101 + 31525841 = 31525942
  • 131 + 31525811 = 31525942
  • 179 + 31525763 = 31525942
  • 293 + 31525649 = 31525942
  • 353 + 31525589 = 31525942

Showing the first eight; more decompositions exist.
