Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690402, here are decompositions:

  • 3 + 8690399 = 8690402
  • 31 + 8690371 = 8690402
  • 43 + 8690359 = 8690402
  • 109 + 8690293 = 8690402
  • 181 + 8690221 = 8690402
  • 199 + 8690203 = 8690402
  • 211 + 8690191 = 8690402
  • 229 + 8690173 = 8690402

Showing the first eight; more decompositions exist.
