Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454904, here are decompositions:

  • 23 + 31454881 = 31454904
  • 31 + 31454873 = 31454904
  • 37 + 31454867 = 31454904
  • 67 + 31454837 = 31454904
  • 163 + 31454741 = 31454904
  • 167 + 31454737 = 31454904
  • 223 + 31454681 = 31454904
  • 251 + 31454653 = 31454904

Showing the first eight; more decompositions exist.
