Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492038, here are decompositions:

  • 5 + 31492033 = 31492038
  • 7 + 31492031 = 31492038
  • 79 + 31491959 = 31492038
  • 157 + 31491881 = 31492038
  • 197 + 31491841 = 31492038
  • 251 + 31491787 = 31492038
  • 311 + 31491727 = 31492038
  • 359 + 31491679 = 31492038

Showing the first eight; more decompositions exist.
