Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625380, here are decompositions:

  • 31 + 8625349 = 8625380
  • 37 + 8625343 = 8625380
  • 67 + 8625313 = 8625380
  • 79 + 8625301 = 8625380
  • 151 + 8625229 = 8625380
  • 193 + 8625187 = 8625380
  • 307 + 8625073 = 8625380
  • 367 + 8625013 = 8625380

Showing the first eight; more decompositions exist.
