Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599040, here are decompositions:

  • 101 + 31598939 = 31599040
  • 107 + 31598933 = 31599040
  • 113 + 31598927 = 31599040
  • 131 + 31598909 = 31599040
  • 167 + 31598873 = 31599040
  • 173 + 31598867 = 31599040
  • 251 + 31598789 = 31599040
  • 257 + 31598783 = 31599040

Showing the first eight; more decompositions exist.
