Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625838, here are decompositions:

  • 5 + 8625833 = 8625838
  • 17 + 8625821 = 8625838
  • 29 + 8625809 = 8625838
  • 131 + 8625707 = 8625838
  • 149 + 8625689 = 8625838
  • 197 + 8625641 = 8625838
  • 239 + 8625599 = 8625838
  • 251 + 8625587 = 8625838

Showing the first eight; more decompositions exist.
